Artistic Surface Rendering Using Layout of Text
An artistic rendering method of free-form surfaces with the aid of half-toned text that is laid-out on the given surface is presented. The layout of the text is computed using symbolic composition of the free-form parametric surface S(u, v) with cubic or linear Bézier curve segments C(t) = {cu(t), cv(t)}, comprising the outline of the text symbols. Once the layout is constructed on the surface,...
متن کاملAutomated Shader Generation using a Shader Infrastructure
Programmable rendering on the GPU (Graphics Processing Unit) utilizing “shader” technology has become a recognized benefit to visual simulation, providing unprecedented realism and fidelity to synthetic environments. However, effective use of shaders is a technological challenge, where implementation of even a trivial vertex or fragment shader requires manual re-implementation of the fixed-func...
متن کاملReal-time Multiresolution Rendering for Dynamic Terrain
This paper presents a novel dynamic terrain multiresolution rendering method by utilizing the capabilities of current generation GPUs. Firstly, the terrain depth offset map texture that represents the appropriate offset values is generated through rendering to texture, which is used to deform terrain in vertex shader. Then in order to accurately represent the fine terrain detail created by defo...
متن کاملReal-time Shader Rendering for Crowds in Virtual Heritage
We present a method of fully dynamically rendered virtual humans with variety in color, animation and appearance. This is achieved by using vertex and fragment shaders programmed in the OpenGL shading language (GLSL). We then compare our results with a fixed function pipeline based approach. We also show a color variety creation GUI using HSB color space restriction. An improved version of the ...
متن کاملReal-time Rendering with Wavelet-Compressed Multi-Dimensional Datasets on the GPU
We present a method for using large, high dimension and high dynamic range datasets on modern graphics hardware. Datasets are preprocessed with a discrete wavelet transform, insignificant coefficients are removed, and the resulting compressed data is stored in standard 2D texture memory. A set of drop-in shader functions allows any shader program to sample the wavelet-encoded textures without a...
