Based on this concept, a number of real-time applications such as collision detection or 3D clipping against multiple volumes can be implemented efficiently using programmable hardware. One major drawback of this image-based representation is the high video memory consumption. To compensate that disadvantage, this paper presents a concept and associated algorithms that enable a lossless, efficient LDI representation which is especially designed for the usage within shader programs. The concept comprises the application of a viewpoint selection, a cropping, and a compression algorithm. We evaluated our algorithm with different test cases and show possible use cases.Categories and Subject Descriptors (according to ACM CCS): I.3.1 [Computer Graphics]: Graphics processors; I.3.5 [Computer Graphics]: Boundary representations; I.3.6 [Computer Graphics]: Graphics data structures and data types;
