Viewing Large Meshes
Other Display Options
Model cloud shading options are accessed under the 3D Model | Shader tab of the Settings box and the Shader toolbar shown below.
Interpolates lighting over polygon faces in a stepped manner given a cel shaded or cartoon like appearance. Results are best on curved surfaces.
Outlines the model with a pen-like line.
Switches model lighting on/off. Note that this does not effect lighting of other object types.
The effect of these shaders is illustrated below.
No Shading (or flat shading)
Smooth shading with Lighting on
Cel Shading without Outline
When viewing large meshes, such as those models generated from scan data, the following should be taken into account:
The following model display options are accessed under the Model | Display tab of the Settings box.
Degrade to points to maintain framerate
Degrades the solid display of models to a points display to improve performance whilst navigating. This is very effective on large dense meshes but may produce an undesirable drop-out effect.
Enables display of textures on models where available.
Renders both sides of a models faces. Use this option if face vertex order does not correctly indicate the direction of the face, ie you see holes in your model.
Cull Back Faces
Prevents faces facing away from the viewer from being rendered. This may improve performance slightly in some cases. This option is not compatible with the last option.
Z Order Transparency
Renders transparent faces in the correct order. This option improves rendering quality but may reduce performance.
