(TextureOcclusion)
- Category:
/Texture/Raytrace - Default object name:
occlusion
Description#
Computes occlusion shading
Attributes#
| Name | Type | Description |
|---|---|---|
| Pass Through | bool |
If checked, the current texture is not evaluated and the value of the attribute selected in Pass Through Attribute is directly forwarded. |
| Master Input | string |
Name of the attribute that will be used as output if Pass Through is enabled. |
| Invert | bool |
If checked, the texture is inverted. |
| Opacity | double |
Set the opacity of the texture. |
| Color | double[3] |
Set the color. |
| Occlusion Mode | long |
Set the type of occlusion. |
| Normal Mode | long |
Set the normal to use to compute the occlusion. |
| Occlusion Color | double[3] |
Set the color of the occlusion. |
| Occlusion Gain | double |
Set the gain of the occlusion. |
| Occluders | reference (Group) |
Define which geometries are occluders. By default it uses the 3D layer geometries. |
| Radius | double |
Set the radius of the occlusion. |
| Angle | double |
Set the opening angle of the hemisphere used at each fragment. |
| Evaluate Transparency | bool |
Enable the computation of the shading for occluding objects. If occluding objects are transparent, this affects the color of the occlusion. |
| Sample Count | long |
Set the sample count used for the sampling. A high value gives a better result but increases the computation time. |
| Bias Mode | long |
Specify if the value of the bias is absolute or if it is relative to the slope on the geometry. |
| Space Mode | long |
Set the space to use when applying a bias. |
| Bias | double[3] |
Apply a bias on the normal. |
| Slope Threshold | double |
Set the minimum angle that a surface must have in order to be considered as a slope. This value corresponds to the angle between the bias direction and the normal of the surface. |
| Merge Objects | bool |
When activated, rays ignore the surface of two objects that are in contact. |
| Merge Threshold | double |
Maximum distance under which the objects are merged. |
| Normal Falloff | curve |
Controls the intensity of the occlusion according to the dot product between the normal of the shaded fragment and the normal on the occluder. |
| Distance Falloff | curve |
Controls the intensity of the occlusion according to the distance. |
