Function Documentation

OSGPPU_EXPORT unsigned int osgPPU::computeTextureSizeInBytes

(

osg::Texture *

tex

)

Compute memory size in bytes, which is allocated by the texture.

OSGPPU_EXPORT osg::Uniform::Type osgPPU::convertTextureToUniformType

(

osg::Texture *

tex

)

Utility function to derive uniform type based on the given texture.

OSGPPU_EXPORT GLenum osgPPU::createSourceTextureFormat

(

GLenum

internalFormat

)

Utility function to derive source texture format from the internal format. For example GL_RGB16F_ARB corresponds to GL_RGB
