Enumeration Type Documentation

enum InterpolationMode

The InterpolationMode affects which value is taken when the ray samples through the data-space. Enumerator: IM_NearestNeighbour  at each sample the nearest voxel is taken. this produces sharp edges but is much faster than Interpolations IM_Trilinear  at each sample the value is trilinear interpolated by the 8 voxels forming the vertices of the cell. this produces smooth images but costs a lot performance

enum RenderMode

The RenderMode affects the order in which the ray get's through the data-space. Choosing between the different Rendermodi does not have a (noticable) effect on the final image, but it does affect performance. Enumerator: RM_FrontToBack  Color is yielded from front (the image-canvas) to back. stops because all colors behind have no effect. therefore its much faster than BackToFront-Mode. if the total opacity>=254 the algorithm RM_BackToFront  Color is yielded by compositing all Ray-Points from back to front.
