因为DirectX和OpenGL的不同，法线贴图也会出现不同的情况。最常见的就是当把模型导入到Substance Painter中时，有一个选项需要选择是法线贴图格式。根据纹理坐标的定义，OpenGL的第一个像素在底部，而DirectX的第一个像素在顶部。也就意味着我们要反转RGB通道中的Green通道。举一个例子，在max中UVW是三个轴向。U代表...
对于缓冲区的分配,大抵还是一致,分为Vertex和Index。 唯一的不同就是:OpenGL是支持先输入所有顶点,再输入所有其它属性的如 顶点顶点顶点 法线法线法线 颜色颜色颜色 DirectX12倒是目前没有遇到过这种用法,一般都是 顶点颜色法线,顶点颜色法线类似排列好的组合 列出对于OpenGL的实现: glEnableVertexAttribArray(0);glVer...
However... I was not able to export 16bit PNG Normals. The only way to get a Normal map in 16bit was to either use the Default Export preset... which is locked to DirectX... or to use my own custom preset which I set up in Substance Designer (which is what ...
Microsoft's DirectX. Most of the graphics on the cronodon.com are rendered on Pov-Ray. Pov-ray is excellent for doing non-interactive graphics, such as still snapshots or animationsIn this section Bot will show you some of the basics of OpenGL and maybe we will even produce a simple 3D...
Vulkan是OpenGL的下一代版本,和DirectX 12一样都是基于AMD私有的Mantle API,不同的是Vulkan是开源的图形API,它承诺通过给予开发者访问硬件底层

1.Vertex Shader,简称VS 2.TESS Control Shader (D3D11 叫Hull shader),简称TCS 3.TESS Evaluation Shader (D3D叫Domain shader),简称TES 4.Geometry Shader ,简称GS 5.Fragment Shader(D3D叫Pixel Shader),简称PS 我将根据他们的“主要”输入与输出,以及其基本功能进行对比。这样我们就可以很好的了解他们在OpenG...

Direct3D designates uniform data as "constant buffers," which, like uniforms, contain constant data provided to individual shaders. As with uniform buffers, it is important to pack the constant buffer data in memory identically to the way the shader expects to interpret it. Using DirectXMath ...
