SoView2DExtensionSampler¶

InventorModule¶

genre	`View2DExtended`
author	`MeVis Medical Solutions AG`
package	`MeVisLab/Standard`
dll	`SoView2D`
definition	SoView2DShader.def
inherits from	`SoView2DExtension`
keywords	`GLSL`

Purpose¶

The SoView2DExtensionSampler module allows for rendering SoView2D extensions to a texture. This texture can be given a name and can be rendered/accessed by a SoView2DShaderOverlay. A typical use case would be to render a SoView2DScene to a texture using this module and to write a custom SoView2DShaderFunction which modifies the rendering depending on the content of the texture.
