The JS cursor and mouse coordinates of the page. Baidu statistics has a hotspot Statistical Chart. What we need to do is to obtain the pixel coordinates of the cursor. Recently, we developed the page statistics for website development. Although we have also developed it before, it is not fully functional, so I will use some good functions this time. For example, in this case, the JS cursor/mouse coordinates of the page may ask you what is the use.

The previous chapter I wrote the rendering pipeline, the middle mentioned the role of shader, our big shader classmate is responsible for the CPU assigned to the GPU to do some such as vertex conversion, care model, rasterization and other operations.There are two types of big shader, they are vs "vertex shader" and Ps "pixel shader".They can exist at the same time, or they can exist separately, without any use restrictions.At that time, if it existed

Challenge: Compile diffuse per pixel shader As a small challenge to be more familiar with shader, you can write a simple diffuseperpixel shader, which works in the same way as specularper pixel shader, but eliminates the mirror reflection. Diffuseperpixel is usually used in non-glossy materials. To switch specularperpixel and diffuseperpixel, you should create two technique types in the simpleshader. FX fi

andJIs the column number. The pixel at the upper left corner is at row 0 and column 0. The second line is a non-empty list of at most 32 words, separated by spaces. valid words are the keywordsid, rot, sym, bhsym, bvsym, Div and mix, or a keyword followed ''-". each keyword key designates an elementary transform (as defined by Figure 1), andkey-designates the inverse of transform key. for instance, rot-is the inverse of counter-clockwise 90o rotation

Using pixel fog Use the following steps to enable pixel fog in your application. Enable fog blending by setting the d3drs_fogenable render state to true. Set the desired fog color in the d3drs_fogcolor render state. Choose the fog formula to use by setting the d3drs_fogtablemode render state to the corresponding member of the d3dfogmode enumerated type. Set the fog parameters as desired fo
