“…Debry et al [9] and Benson and Davis [10] have shown how 3D hierarchical data structures, named octree textures, can be used to efficiently store color information along a mesh surface without texture coordinates. The idea of using a multi-resolution hierarchy in point data was first introduced by Rusinkiewicz and Levoy in QSplat [11].…”

LiDAR (light detection and ranging) 3D points (both terrestrial and airborne) have recently become a prevalent type of geospatial data. However, this large-scale data poses significant technical challenges for efficient access and visualization. One approach is to generate points with different density levels, i.e. multi-resolution data sets that can be used for various purposes. This paper presents a simple static tree-based approach and discusses implementation alternatives in favour of speeding up tree building and point sampling processes. This approach is generic and can be applied to other geographic data types as well.

“…This concept was extended independently by Benson et al with octree textures [9] and by DeBry et al with octexes [10], both of which compensate for the poor performance of 2D MIP maps on complex 3D surfaces.…”

“…Disregarding incoherent geometry can result in a number of problems, most notably that of boundary bias at edges and corners which can cause perceptible energy loss in many scenes. In addition, light and shadow leaks under geometry may also appear in certain models (see [9], [10], [13] for examples).…”

Abstract-Photon mapping is an efficient method for producing high-quality, photorealistic images with full global illumination. In this paper we present a more accurate and efficient approach to final gathering using the photon map based upon hierarchical evaluation of the photons over each surface. We use the footprint of each gather ray to calculate the irradiance estimate area rather than deriving it from the local photon density. We then describe an efficient method for computing the irradiance from the photon map given an arbitrary estimate area. Finally, we demonstrate how the technique may be used to reduce variance and increase efficiency when sampling diffuse and glossy-specular BRDFs.

“…Remeshing can be used to improve the triangle shapes, to vary the triangle size according to curvature details, and to induce semi-regular tessellations. Recently, octrees have been used to store colors in 3D for surface texturing without any parameterization [Benson and Davis 2002;DeBry et al 2002]. Although octree techniques are supported with programmable GPU's, they are not yet directly supported by graphics hardware.…”

Feature-based surface parameterization and texture mapping

Surface parameterization is necessary for many graphics tasks: texture-preserving simplification, remeshing, surface painting, and precomputation of solid textures. The stretch caused by a given parameterization determines the sampling rate on the surface. In this article, we present an automatic parameterization method for segmenting a surface into patches that are then flattened with little stretch.Many objects consist of regions of relatively simple shapes, each of which has a natural parameterization. Based on this observation, we describe a three-stage feature-based patch creation method for manifold surfaces. The first two stages, genus reduction and feature identification, are performed with the help of distance-based surface functions. In the last stage, we create one or two patches for each feature region based on a covariance matrix of the feature's surface points.To reduce stretch during patch unfolding, we notice that stretch is a 2 × 2 tensor, which in ideal situations is the identity. Therefore, we use the Green-Lagrange tensor to measure and to guide the optimization process. Furthermore, we allow the boundary vertices of a patch to be optimized by adding scaffold triangles. We demonstrate our feature-based patch creation and patch unfolding methods for several textured models.Finally, to evaluate the quality of a given parameterization, we describe an image-based error measure that takes into account stretch, seams, smoothness, packing efficiency, and surface visibility.
