DESCRIPTION

This free tool displays the 3D geometry (including colours, textures, level-of-detail, state, articulated parts, and shading) of the <Model>s and <Image>s of the given transmittal using OpenGL. Information about the images and models being loaded from the SEDRIS transmittal are printed to stdout. Once the images and models are loaded, the viewer will open the 3D-view window, and proceeds to sequence through and display all of the images loaded. After all of the images have been displayed, the first root model in the model library is displayed. The window then waits for user control from the keyboard. The 3D-view window can be moved, resized, minimized, and maximized. When the 3D-view window is selected, the models and images can be selected, viewed, and controlled via keyboard and mouse commands.

RELEASE INFORMATION

The current version is 4.1.4.0, and is compatible with SEDRIS SDK 4.1.x.

FEATURES

• Ability to change orientation and distance of models for accurate viewing using the mouse or keyboard.
• Ability to change background colour.
• The display mode (fill, wireframe, or outline) of the geometry in a model can be controlled by the user.
• The rendering of blended textured geometry can be toggled.
• The geometry of models can be shown with or without texture mapping turned on.
• The user may enable or disable the internal use of OpenGL display lists.
• The user can toggle between viewing the textures from the <Image Library> of the input transmittal, if one is present, and the models from the <Model Library>.
• The user can control the quality of texture rendering.
• The user can step through the images or models.
• The light source and its characteristics can be controlled.
• When in model viewing mode, Model Viewer can print out the data structure of the current model and current viewing parameters.
• Models with articulated parts can be animated.
• Models containing <State Related Geometry> can be controlled by the user.
• Models containing <Level Of Detail Related Geometry> can be controlled by the user.

LIMITATIONS

• Other data, such as <Data Tables>, <Features>, <Geometry> under the <Environment Root>, and topology are not viewable with this application.
• Editing of data is not supported by this application.
• The Environment Root is not displayed (i.e., terrain is not handled).
• Lighting and shading are not handled correctly for all cases.
• Multiple transparencies are not handled correctly.
• Features are not displayed.
