The paper presents efficient image-based rendering methods capable of generating multiple frames per second on a PC. The first method, Sprites with Depth, warps sprites with depth information to represent smooth surfaces without gaps. The second method, Layered Depth Images (LDI), is applicable to more complex scenes and involves warping from an intermediate representation. LDI stores multiple depth pixels at each pixel location, allowing for proper alpha blending without depth sorting. The paper discusses the advantages of LDI, including linear growth in representation size with depth complexity and efficient rendering using McMillan's ordering algorithm. The authors also describe the implementation details of Sprites with Depth and LDI, including the use of backward mapping and incremental warping algorithms. The results demonstrate the effectiveness of these methods in generating realistic and efficient image-based renderings.The paper presents efficient image-based rendering methods capable of generating multiple frames per second on a PC.
