Visibility Driven Rasterization

چکیده
Cotton-picker dataset containing 10 million triangles. Occlusion culling in z-buffer systems has drawn a lot of attention over the last few years.1,3 Due to the high computational costs of occlusion queries, hardware support is required to accelerate interactive rendering. This requires mechanisms that fit nicely into an available graphics subsystem without greedily consuming chip real estate (one reason why hardware support for occlusion culling is rare).

Visibility Driven Rasterization
We present a new visibility driven rasterization scheme that significantly increases the rendering performance of modern graphic subsystems. Instead of rasterizing, texturing, lighting, and depth-testing each individual pixel, we introduce a two-level visibility mask within the rasterization stage which facilitates the removal of groups of pixels and triangles from rasterization and subsequent ...
متن کاملVisibility Culling per Cache Block with Tiling-Traversal Algorithm
As many applications in computer graphics require render high complex 3D scenes at interactive rates, the search for an effective visibility culling method has become one of the most important issues to be addressed in the design of 3D rendering processors. In this paper, we proposed a new rasterization pipeline with visibility culling; the proposed architecture performs the visibility culling ...
متن کاملA Fast Scanline Micro-Rasterization Kernel and its Application to Soft Shadows
Many soft shadow algorithms approximate the visibility integral via sampling occlusion at many locations on the light source. We present a fast micro-rasterization kernel to efficiently handle a grid of such sample locations by micro-rasterizing triangular occluders onto planar lights. Our bit-parallel scanline algorithm iterates over relevant scanlines and clears occluded samples using a small...
متن کاملA Voxel-based Rendering Pipeline for Large 3D Line Sets
We present a voxel-based rendering pipeline for large 3D line sets that employs GPU ray-casting to achieve scalable rendering including transparency and global illumination effects that cannot be achieved with GPU rasterization. Even for opaque lines we demonstrate superior rendering performance compared to GPU rasterization of lines, and when transparency is used we can interactively render la...
متن کاملSampled and Analytic Rasterization
Hidden surfaces eliminated Sorting To enable visibility prefiltering, the visible parts of the projected scene primitives have to be determined exactly. We employ parallel hidden surface elimination for this task. The computations can be executed in parallel for all edges of the input triangles. This provides sufficient data parallelism to effectively use massively parallel hardware such as GPU...
