1.使用SOIL2实例化OpenGL纹理对象并读取数据; 2.调用glBindTexture()以生成新创建的纹理; 3.使用glTexParameter()函数调整纹理设置,返回可用的OpenGL纹理对象的整数ID。 GLuint loadTexture(const char *texImagePath) { GLuint textureID; textureID = SOIL_load_OGL_texture(texImagePath, SOIL_LOAD_AUTO, SOIL...
Texture Mapping in OpenGL is a fairly straightforward concept. Every texture is nothing but an image of some sort. Texture mapping is basically applying a texture to a surface. Textures can be 1D, 2D or even 3D. A 1D texture is an image with either a width or a height, not both. They...

is the basis for shadow mapping, lightmap, and texture decal. 此示例演示了投影纹理贴图,这是阴影贴图,光照贴图和纹理贴花的基础。 In regular texture mapping, the texture coordinates from each vertex is static, often calculated in the modeling software such as Maya, 3DS Max, or Blender. In proje...

首先,代码采用自己写的LoadBMP函数载入位图数据,之后绑定并且生成对应的纹理对象.相应的代码如下: //Load The Bitmap, Check For Errors, If Bitmap's Not Found Quit if(TextureImage[0]=LoadBMP("Data/NeHe.bmp")) { Status=TRUE;//Set The Status To TRUE ...
could also apply textures to the wallpaper and carpet. For example, you could use a scanned image of your mother to texture-map a picture frame on the wall. The Doom video game almost exclusively uses texture mapping (but not through OpenGL) to create the feeling of being in scary places...
该过程称为 texture mapping (纹理映射),注意区分 texture map (纹理贴图)。 纹理坐标经过corresponder functions (响应函数) 来到texture space (纹理空间), 在这个例子中贴图分辨率为 256×256 ,那么直接将当前坐标乘上分辨率即可得到坐标 ( 81.92,74.24) ,去掉小数部分得到坐标 (81,74) ,即 texel texture (纹...

【OpenGL】投影纹理映射(Projective Texture Mapping) 一、纹理投影映射简介 投影纹理映射用于映射一个纹理到物体上,好比将幻灯片投影到墙上一样。 投影纹理映射经常在一些阴影算法以及体绘制(Volume Rendering)算法中用到。严格的说,只要涉及到“纹理实时和空间顶点对应”,通常都要用到投影纹理映射技术。
