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.
Celshader
Interpolates lighting over polygon faces in a stepped manner given a cel shaded or cartoon like appearance. Results
are best on curved surfaces.
Outline
Outlines the model with a pen-like line.
Lighting
Switches model lighting on/off. Note that this does not effect lighting of other object types.
The effect of these shaders is illustrated below.

When viewing large meshes, such as those models generated from scan data, the following should be taken into
account:
| * | The OBJ file importer is designed to import large meshes. Other import types may not import large meshes successful. |
| * | Large meshes of a single material display faster than those with multiple materials. |
| * | Switching off the Double Sided option may improve performance. |
| * | Switching on Back-face Culling may improve performance. |
| * | Using the Cel or Ouline shader will drastically reduce performance. |
| * | Consider using the Degrade to Points option for fast navigation around objects. |
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.
Texturing
Enables display of textures on models where available.
Double Sided
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.
