getIndexMatrix()

template<unsigned int N>

glm::dmat4 inviwo::StructuredGridEntity< N >::getIndexMatrix

(

)

const

Returns the matrix transformation mapping from texture coordinates to voxel index coordinates, i.e. from [0,1] to [-0.5, number of voxels-0.5]

Note

Data is centered on the voxel, see OpenGL specifications, figure 8.3 http://www.opengl.org/registry/doc/glspec43.core.20120806.pdf or for instance http://bpeers.com/articles/glpixel/
