While the primary purpose of picogen is to display realistic 3D terrain, both in terms of terrain formation and image plausibility, it also is a heightmap-creation tool, [1] in which heightmaps are programmed in a syntax reminiscent of Lisp. [2] The shading system is partially programmable. [3]
In computer graphics, a texture atlas (also called a spritesheet or an image sprite in 2D game development) is an image containing multiple smaller images, usually packed together to reduce overall dimensions. [1] An atlas can consist of uniformly-sized images or images of varying dimensions. [1]
Bump mapping [1] is a texture mapping technique in computer graphics for simulating bumps and wrinkles on the surface of an object. This is achieved by perturbing the surface normals of the object and using the perturbed normal during lighting calculations. The result is an apparently bumpy surface rather than a smooth surface, although the ...
Bryce 7 was released in July 2010. New features include the Instancing Lab and advanced lighting. Updated features include the Daz Studio Bridge, the Sky Lab, clouds and HDRI. Bryce 7 is available in three versions, a limited free version, a standard version lacking the new features and a pro version with the new features. [15]
A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture.They may be stored in common image file formats, referenced by 3D model formats or material definitions, and assembled into resource bundles.
Some applications benefit from using artificial textures, such as elevation coloring, checkerboard, or other generic textures. Some applications attempt to recreate the real-world surface to the best possible representation using aerial photography and satellite imagery. In video games, texture splatting is used to texture the terrain surface.
Procedurally generated tiling textures. In computer graphics, a procedural texture [1] is a texture created using a mathematical description (i.e. an algorithm) rather than directly stored data. The advantage of this approach is low storage cost, unlimited texture resolution and easy texture mapping. [2]
A normal pointing to right of the texture (1,0,0) is mapped to (255,128,128). Hence the right edge of an object is usually light red. A normal pointing to top of the texture (0,1,0) is mapped to (128,255,128). Hence the top edge of an object is usually light green. A normal pointing to left of the texture (-1,0,0) is mapped to (0,128,128).
