What's the difference between these two directories when you recently used studio to discover that drawle-hdpi was not replaced by mipmap-hdpi? There is no difference in use, you use it as a drawable. However, using the MIPMAP system will provide some performance optimizations on the scale.

Our algorithms are easilyGPUOnly a little bit of data needs to be stored. 1 Introduction Shadow maps [Williams 1987]And shadow(Shadow volumes) [Crow 1977]It is a common shadow rendering algorithm.Shadow mapsCompared with a shadow, a shadow has many advantages. For example, it is easier to execute, less sensitive to model complexity, and has no special geometric space requirements. unfortunately, like most textures, shadow maps If the filter is ina

will treat the texture as a 2D plane. Interpolation is interpolated by the shortest route between vertices. Then under the 2D plane. It's going to be a line segment.Texture packaging refers to the texture in the interpolation of the time, is no longer a 2D plane, such as in the U direction of packaging, is the texture around a cylindrical surface, this time the shortest distance between two vertices is the shortest distance on the cylinder surface and no longer the shortest distance on the plan

-functional systems often have to deal with sudden data bursts, such as IP data packets or code similar to the framework in more complex modem standards. The core and system requirements of these applications are sometimes different from those of stream applications, and xdais rules must contain two types of data throughput. There is a feature that has not changed, that is, the overhead needs to be kept at a low level. Experience shows that DSP customers and third parties will accept performan

, it is to use the element closest to the pixel as the color. Align the texture coordinates to the nearest integer, and then use the texture map at the integer coordinates as the final color. This method may cause some errors when processing the graphic border. Linear texture filtering uses bilinear texture filtering in Direct3D. It calculates the average value of the four elements closest to the sampling point. The configuration is as follows:M_pd3Device-> SetSamplerState (0, D3DSAMP_MINFILTER,

recommends that simple shader do not do this. (Don't do this inSimple shader ).18. If possible, use vertex shader instead of pixel shader to change the calculation from pixel-by-pixel to vertex-by-vertex.19. Minimize the texture size. A large texture may overload the texture cache, leading to reduced hit of the texture cache. A large texture may overload the Display memory,At this time, the texture is obtained from the system memory.20. As long as it is possible to use a 16-color texture, such

Here are some works great render optimization ideas: 1) Cull the back surface; 2) Use view frustum culling; 3) Less draw call number; 4) Batch those meshes that with the same materials; 5) Use simpler shader, consider carefully lighting in vertex shader or pixel shader; 6) Smaller texture or use mip-maps, hardware supported compression; 7) Use multiple instance instead of draw one mesh several times; 8) Use vertex buffer objects or vertex array; 9) Se

and have exceeded the consumption of ssao and shadowmask. The two are the blocks that occupy the largest screen pixels in the terrain system. By analyzing their shader assembly, we found that the number of samples per pixel reached an astonishing 26! (Zpass 7 times, General pass 19 times) 3. Select tex2dlevels and tex2dgrad However, we can see that the number of tex_ld and tex_ldl is not that large. By searching, we can find that the original tex2dlays function can explicitly specify the number

second parameter is texture_wrap_s and exture_wrap_t, corresponding to the X and Y directions respectively. The third parameter is repeat, clamp_to_edge, and mirrored_repeat. For details about their effects, see OpenGL.Chapter 9 texture/texture coordinate packaging in ES 2.0 programming guide. In addition, when the width and height of the texture image are not the integer power of 2, the packaging mode can only be gl_clamp_to_edge, and the narrow filtering mode can only be gl_nearest or gl_line
