|
diffuse = vizfx.DIFFUSE_LAMBERT
The diffuse shading model. Can be one of the following flags:
vizfx.DIFFUSE_LAMBERT | Use the standard Lambert diffuse model. |
vizfx.DIFFUSE_HALFLAMBERT | Use the Half-Lambert diffuse model popularized by Valve. This produces a wider falloff which results in softer shading. |
specular = vizfx.SPECULAR_PHONG
The specular reflectance model. Can be one of the following flags:
vizfx.SPECULAR_OFF | Disable specular lighting. |
vizfx.SPECULAR_BLINNPHONG | Use the Blinn-Phong specular model. |
vizfx.SPECULAR_PHONG | Use the Phong specular model. |
diffuseRamp = None
An optional <texture> object for ramped diffuse lighting. The computed diffuse intensity will be used as a lookup into the ramp texture, and the resulting color sample is applied to the diffuse lighting color. The ramp texture is typically a 256x1 image, where the left side represents the color when the surface is facing away from the light, and the right side represents the color when the surface is facing the light.
Remarks
Creates a lighting model effect that can be applied to a <composer> or <node>.
Return Value
<effect> object
Example
# Create Half-Lambert lighting model effect
effect = vizfx.addLightingModel(diffuse=vizfx.DIFFUSE_HALFLAMBERT)
# Apply to default composer (replaces default lighting model effect)
vizfx.getComposer().addEffect(effect)
