SoShaderParameterPlane¶

InventorModule¶

genre	`Shader`
author	`MeVis Medical Solutions AG`
package	`MeVisLab/Standard`
dll	`SoShader`
definition	SoShader.def
keywords	`vertex`, `fragment`, `geometry`

Purpose¶

The module SoShaderParameterPlane provides a means to set a plane uniform parameter. This can be used to, e.g., calculate the distance from a point to a plane in a shader.

Output Fields¶

self¶

name: self, type: SoNode¶

Parameter Fields¶

Visible Fields¶

Name¶

name: name, type: String¶: Sets the name of the parameter.

Value¶

name: value, type: Plane, default: 0 0 1 0¶: Sets the parameter value.

Transform To Eye Coordinates¶

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

If checked, the plane is transformed to eye coordinates, using the current model-view matrix of the Open Inventor state.

This can be useful if using the plane in a shader and can avoid the matrix multiplications that would otherwise have to be performed in the shader.
