Design works in Autodesk Showcase
Save time and means. Make well-founded design decisions by means of technology of digital prototypes. The program for visualisation Autodesk Showcase allows to receive on the basis of design 3D the data exact and realistic images for an effective exchange of plans and ideas.

The program allows to represent and look through different variants of the project in a natural environment. Thus with the maximum realness materials, illumination and surrounding conditions are displayed. By means of Autodesk Showcase members of design collective can make well-founded decisions – as locally, and through remote sessions. As a result process of the statement of projects becomes effective and economic.

Autodesk Showcase – the software product intended for visualisation of projects at use of technology of digital prototypes Autodesk. He allows design, design and marketing collectives quickly and effectively to create exact and realistic images on the basis of the data 3D CAD for the purpose of transfer of the conceptual information and creation of an information context for a wide audience. Participants of collectives can make decisions as on workplaces, and remotely.

Let's consider preparation of the data.
3D-models are imported from Autodesk Alias or from CAD in Autodesk Showcase or Autodesk Showcase Professional, and then will be transformed to a format used for high-quality interactive 3D-visualisation.

Let's consider visualisation of the data from Autodesk Alias and CAD.
Import of 3D-given is made by means of means Autodesk DirectConnect. Among supported formats – AutoCAD Inventor, DWG, APF, STEP, IGES, SGI OpenInventor, CSB and STL. For other formats of CAD, such as JT, UGS NX, Catia V4/V5, SolidWorks and ProENGINEER/Granite, it is necessary to get compilers of data Autodesk DirectConnect separately.

Let's consider the import filter.
Magazine Autodesk DirectConnect files allow to add filters at import of scripts that depending on layers and materials to filter unnecessary geometry. It allows to save time.

Let's consider maintenance of a data structure and the visual information from a source.
From files of CAD the maximum of the information necessary for qualitative representation 3D of the data is imported. At import the data structure – hierarchy, layers, levels of components remains. Showcase can create one file on the basis of several sources without loss of history of the brought changes.

Let's consider the automated substitution of materials.
There is a possibility of automation of repeating actions on substitution of suitable materials of imported geometry. Thus the material choice is made on the basis of the data about names, layers and the colours set in initial CAD.

Let's consider units of measure.
Depending on the set units of measure, Showcase scales the imported data, displaying the true sizes of model.

Let's consider updatings of design model.
Showcase supervises the initial data and notifies the user on brought changes. The appendix automatically applies options 3D the visualisation set in the previous version.

Let's consider optimisation of the data for 3D-visualisation.
Showcase allows to raise quality of visualisation thanks to a qualitative triangulation of models without cracks. Algorithms of transformation Showcase transfer in the beginning to interactive visualisation results with quality, greatest possible for the limited set of initial geometry.

At import files selectively break into cells, and in them some levels of detailed elaboration are created. It raises productivity and allows to keep even fine details. That surfaces were convenient for processing, at import they are automatically sewed. Sewing together procedure takes into consideration affinity to adjacent surfaces, the organisation of layers and appointment of materials.

Let's consider the organizer of the data.
The correct data structure simplifies access to them in the course of visualisation. The data is ordered on components and materials; at renamings the initial data structure is not broken.

Let's consider creation of shades from surrounding conditions.
Shades do the image by more realistic. Showcase allows to appoint structures of natural illumination of all model or to its separate fragments.

Let's consider maintenance of symmetry of models.
Modelling of symmetric objects can be accelerated considerably. For this purpose it is necessary to import only half of model, and then by means of function Mirror to finish second half.

Let's consider realistic display of realistic materials.
That virtual prototypes looked is realistic, it appoints high-quality materials from library. Such materials as an automobile paint, glass, a skin, metal, plastic, etc., are created by professionals in the field of visualisation. You can adjust materials to the needs, adjusting their real parametres.

Let's consider management of materials.
The improved interface allows to operate the user materials and libraries effectively: to edit, keep, delete and transfer on a network.

Let's consider creation of photorealistic Visualisation of models is made in the various environments providing high quality of results. Showcase offers a wide choice of samples of the environment intended for creation of realistic presentations.

Let's consider tools of creation of environment.
Users can create the variants of surrounding conditions, and also to combine already ready combinations. Import of panoramic images with the expanded dynamic range (HDRI) for creation of cards of light exposure is possible also. Users can freely operate cards and adjust geometry to the needs.

Let's consider management of environment models.
It became much more convenient and easier to operate the user models of environment thanks to the new interface of work with the user libraries in Showcase.

Let's consider design alternatives.
Design alternatives can differ with geometry, materials and an arrangement of objects. There is a possibility of a combination of several variants of the project. During presentation switching between variants is carried out by one click of the mouse.

Let's consider the realistic sizes.
For a correct estimation of the real sizes of model it is necessary to set the demanded scale of display.

Let's consider animation on a rotary table.
After the model is located on a rotary table, you set, as it needs to operate. Consideration of model with turn allows to estimate the characteristic features inherent in this or that variant of the project.

Let's consider the task of background images.
Now users can create quickly images of the model placed in any surrounding conditions ready for printing. As a background at model import any 2D-image with the smoothed transition to 3D-geometry can be used.

Let's consider alpha channel creation.
Creation of the images containing the alpha channel, allows to achieve more flexibility at work with images and preparation of elements for catalogues.

Let's consider the integrated algorithm of trace of a beam in real time.
Showcase allows to create high-quality images even to beginners. The integrated trace of a beam in real time provides possibility of a choice of quality of visualisation. It is possible to use preliminary calculated shades or to calculate them independently together with reflexions and refraction. The course of working process does not vary; divergences between OpenGL and the integrated trace of a beam are so insignificant that it is possible to supervise quality and speed parametres. The algorithm of trace of beams uses all accessible program libraries, without demanding additional licensing.

Let's consider export to format Photoshop.
The images received in Showcase, it is possible to keep in files of format Photoshop. Distribution of a background, objects and shades on different layers facilitates editing and processing of images.

Let's consider in more details functionality Autodesk Showcase 2010.
Let's consider preparation of the data.
3D models are imported from Autodesk Alias or from CAD in Autodesk Showcase or Autodesk Showcase Professional, and then will be transformed to a format used for high-quality interactive 3D-visualisation.

It is improved: Visualization of the data from Autodesk Alias and CAD
Import 3D the data is made by means of means Autodesk® DirectConnect. Among supported formats – Autodesk® Inventor®, DWG™, APF, STEP, IGES, SGI® OpenInventor, CSB and STL. For other formats of CAD, such as JT, UGS® NX®, Catia® V4/V5, SolidWorks® and ProEnGiNeErj/Granitej, it is necessary to get compilers of data Autodesk® DirectConnect separately.

Let's consider batch operation, a triangulation (function Showcase Professional).
With a view of simplification of laborious work on transformation of the data out of Showcase and transformations of the big files are used scripts. The task of parametres of transformation allows to adjust work of scripts. Package process of a triangulation can be integrated into existing operations with databases that guarantees timely readiness of the data for visualisation.

Let's consider creation of presentations.
The models prepared in Autodesk® Showcase®, are applied in 3D visualisation and the presentations which are carried out at the statement of projects. Autodesk Showcase and Autodesk Showcase Professional allow to appoint to models realistic materials (an automobile paint, glass, a skin), and for a context estimation to place them in real environment. Ample opportunities of creation of the user materials and environments, and also model components promote acceptance of the weighed design decisions.

It is improved: Realistic materials
That virtual prototypes looked is realistic, it appoints high-quality materials from library. Such materials as an automobile paint, glass, a skin, metal, plastic, etc., are created by professionals in the field of visualisation. You can adjust materials to the needs, adjusting their real parametres.

The novelty: Management of materials
The improved interface allows to operate the user materials and libraries effectively: to edit, keep, delete and transfer on a network.

Let's consider a detail/imposing of materials.
Work with imposing of materials, without thinking of formation of a card of structures. There is a possibility of creation of various variants of registration and their preservation as design alternatives.

It is improved: Creation of photorealistic environments
Visualisation of models is made in the various environments providing high quality of results. Showcase offers a wide choice of samples of the environment intended for creation of realistic presentations.

It is improved: Tools of creation of environment

Let's consider pictures.
In the course of viewing the dynamic chamber allows to be switched quickly between model components. By means of adjustment of parametres of the chamber in movement process it is possible to add various effects. The user chooses a way of transition, a kind in the beginning and in the end of a shot, and Showcase automatically forms a shot. During display of presentations such in advance prepared effects are caused by one click of the mouse.

Let's consider a storyboard (function Showcase Professional).
Fast switching between model variants, change of position of the chamber and transition by the certain moment of a scene are possible by means of the storyboard panel. Change of variants of surrounding conditions, viewing of alternative variants of models, start of testing of functionality, management of the chamber – all it is made by one click of the mouse.

Let's consider additional possibilities of illumination.
The unlimited quantity of sources of illumination allows to operate flexibly a kind of a scene and to deduce on the foreground the important elements of the project.

Let's consider carrying out of presentations and decision-making.
The realistic and exact presentation of 3D-data of CAD created by means of visualisation tools in Autodesk® Showcase® and Autodesk® Showcase® Professional, allows to make the important design decisions. Your colleagues and customers do not remain indifferent to represented models without dependence from, whether there are you in one room or on different continents.

The novelty: the Integrated algorithm of trace of a beam in real time
Showcase allows to create high-quality images even to beginners. The integrated trace of a beam in real time provides possibility of a choice of quality of visualisation. It is possible to use preliminary calculated shades or to calculate them independently together with reflexions and refraction. The course of working process does not vary; divergences between OpenGL and the integrated trace of a beam are so insignificant that it is possible to supervise quality and speed parametres. The algorithm of trace of beams uses all accessible program libraries, without demanding additional licensing.

Let's consider parallel demonstration of the project (function Showcase Professional).
Display of variants of the project in the neighbourhood on the screen gives the chance to estimate distinctions in them. For simultaneous viewing of variants of the project it is possible to load and show some scenes within the limits of one session.

Let's consider joint remote work (function Showcase Professional).
Remote carrying out of presentations for employees allows not to waste time and means for trips. Connection of sessions Showcase to each other on a network opens possibility of joint remote work. If network connection is established, presentations Showcase can be started from the remote main computer. The data thus can either be stored on-line, or extend on a network for maintenance to them of access of users with low throughput of communication channels.

Let's consider an input equipment.
Presentations can cope the most different input equipment – up to game controllers. Thanks to simplicity of the reference with such devices of presentation the persons who do not have special skills are capable to spend even.

Let's consider creation of images with the high permission.
The user can allocate the shot necessary to it and keep it in one of standard formats with the demanded permission, including the alpha channel.

Let's consider export of animations.
Showcase allows to export the separate animations of any permission created on the basis of one or all shots, including transitions. The exported files are intended for the employees who do not have possibilities to work with Showcase. These files can be introduced in presentation.

Let's consider the external user interface (function Showcase Professional).
It is possible to create own interface by means of standard HTML or Macromedia® Flash® editors. Page HTML joins necessary commands Showcase. They operate data Showcase through interface API commands.

The novelty: export to format Photoshop
The images received in Showcase, it is possible to keep in files of format Photoshop®. Distribution of a background, objects and shades on different layers facilitates editing and processing of images.

Let's consider cluster support (function Showcase Professional).
This function allows to deduce images full-scale at once on some projectors or screens, without losing the permission and qualities.
