texture compression

In this tutorial, we will add texture ing to the Terrain Based on illumination and the water surface program, and we will dynamically change the texture coordinates of the water surface based on time to achieve the effect of water surface texture fluctuation. The terrain (Valley) and water surface are all grid-based planes. For terrain, modify the vertex type: S

This chapter mainly introduces the concept of Sprite nodes and texture sets. The simplest way to generate ccsprite is to use a texture map. CCSprite *_firstSp = [CCSprite spriteWithFile:@"icon.png"]; CGSize wins = [[CCDirector sharedDirector] winSize]; _firstSp.position = ccp(_firstSp.contentSize.width/2, wins.height/2); [self addChild:_firstSp z:1]; Animation Frame The above is a basic method to ge

http://blog.csdn.net/zhuyingqingfen/article/details/19331721Category: GLSLProjected texture mapping (projective texture mapping): It is the projection of a texture onto the object of the scene, like a projector projecting a slide onto another object.such as: projecting onto a teapot with the texture image on the leftHo

Rectangle TextureThe texture target is gl_texture_rectangle.First, the rectangular texture cannot be mip-mapped;Then, the rectangular texture is not normalized (actually addressing the pixels)Finally, texture coordinates cannot be duplicated, and texture

Brief introductionTexture caching is a drawing work that caches textures easily. The size, color, and area range of each cached image can be modified. This information is stored in memory and is not sent to the GPU every time it is drawn.CctexturecacheCocos2d caches the sprite's texture by calling Cctexturecache or Ccspriteframecache.When the genie calls the Cctexturecache or Ccspriteframecache method, COCOS2DX uses the

supported Formats supported formatsUnity supports the following file formats:PSD, TIFF, JPG, TGA, PNG, GIF, BMP, IFF, PICT。 It should be noted that unity can import multiple layers of PSD and TIFF files, and the layer will automatically collapse when imported, so you don't have to waste time using the source file type directly. This is important, allowing only one texture copy to be imported into unity using a three-dimensional modeling program from P

D3d implements bitblt capturing texture UV texture addressing I was dull and always thought that d3d textures could only be based on the entire slip texture. Instead of selecting a part of the

how to zoom out or zoom in to fit the image size.If the texture is smaller it needs to be magnified that is done with the magnification function: If the texture is small, use the zoom function to zoom in. // Scale up if the texture if smaller. Gl. glTexParameterf (GL10.GL _ TEXTURE_2D, GL10.GL _ TEXTURE_MAG_FILTER, GL10.GL _ LINEAR ); And how to scale if the

First, texture foundation--Seamless texture production Often in major forums to see questions about seamless texture production, because no matter in the production of 3d map, or Web page, or define the Patten of Photoshop, the texture of seamless convergence has a high demand. Of course, the use of some plug-ins such

gltexsubimage2d functionProvides the ability to modify an image function, because modifying a texture is much less expensive than creating a texture, for some video capture programs can first store the video image in a larger initial image (the image size requirement is 2, OGL 2.0 does not have this limit), create a rendering texture, Then repeatedly call Gltexsu

image.In texture mapping, we need to set several parameters, the first one is to tell OpenGL how to zoom in or zoom out to fit the size when rendering the picture.If the texture is smaller it needs to being magnified that's done with the magnification function:If the map is small, then we need to zoom in using the amplification function.Scale up if the texture i

Study on wood texture Wood... We've seen a lot of it! Furniture, flooring ... There are so many things in life that involve wood. Now the popular wood flavor decoration, today and you talk about the production of wood texture it!It is worth mentioning, my practice is very high, after everyone learned to ensure that three minutes to make a piece of wood out. OK, here we go. 1. Turn on Photoshop (nonsense!),

Generate texture coordinates from the ing point set to the surface of the cylinder Vtktexturemaptocylinder is a filter that generates 2D texture coordinates and maps the input texture dataset to a cylindrical string. The range can be specified by the user or automatically generated. (A cylinder is the center of an automatically generated computing cylinder ). Not

Cloth Research (1)--flax texture Today we are going back to our point, the texture came up. Starting from this section, we begin to look at the various fabrics that are common in life. Well, let's try the linen fabric!1. Press D to set Photoshop to the default color, new file, 250x250pixel.2.

Texture word to make a faster way is to use the texture material directly, you can in the layer style of the texture and pattern overlay two items to add a different material, so that the material by stacking, generate more special texture.
