SoVertexAttribute1ui¶

InventorModule¶

genre	`Shader`
author	`MeVis Medical Solutions AG`
package	`MeVisLab/Standard`
dll	`SoShader`
definition	SoShader.def

Purpose¶

Allows to provide a named vertex attribute to the SoVertexShader shader.

Note that the number of values needs to match the number of vertices of the geometry that is rendered (as given by SoVertexProperty, SoCoordinate3 or SoCoordinate4).

Vertex attributes are only supported when vertex array rendering is used, which is the case for SoFaceSet/SoIndexedTriangleSet/SoIndexedFaceSet/SoLineSet/SoIndexedLineSet/SoPointSet nodes when the PER_VERTEX/PER_VERTEX_INDEXED mapping is used.

Output Fields¶

self¶

name: self, type: SoNode¶: Place this node in front of the shape node that should be rendered.

Parameter Fields¶

Visible Fields¶

Name¶

name: name, type: String, default: attribute1¶: The name of the attribute as used in the shader. If the current vertex shader does not use the attribute, it is not bound.

Per Instance¶

name: perInstance, type: Bool, default: FALSE¶

Values¶

name: values, type: IntegerList, default: 0¶: The values of the attribute.

Normalized¶

name: normalized, type: Bool, default: TRUE¶: If enabled, the values are normalized to [0,1] in the shader
