SoVertexAttributeRotation¶

InventorModule¶

genre	`Shader`

package	`MeVisLab/Standard`
dll	`SoShader`
definition	SoShader.def

Purpose¶

SoVertexAttributeRotation sends SbRotation values as vertex attribute for a shader.

It sends the rotations in quaternion form (four floats), since quaternions can be used easily inside of a GLSL shader. Note that the interface of SoMFRotation takes a list of SbRotation, which are constructed from an axis and an angle (in radians) if specified from a string. There is also a SbRotation constructor that takes four floats instead of axis and angle, which are the four values of a unit quaternion.
