I am also OK with saving in some other image format. It’s a bit different than doing everything in post like I usually do since there is no color management in C4D just sRGB, Linear, Disable and frame buffer is not affected, it works mainly for the materials as I understand. Above each cache line is a miniature rectangle showing where the pixels corresponding to the cache line fall in the framebuffer: The class constructor should allocate the a frame buffer for the IDeckLinkVideoConversion to use via the GetBytes [4] virtual function. When multisampling as opposed to supersampling , not every on-chip pixel is shaded. The following is an example template for this class: Much less on-chip space is needed for good performance compared with a general-purpose frame buffer cache.

In return, the reduction in bandwidth increases the rasterization speed. I am thus moving this to resolved.

OpenGL ES can achieve similar behavior with extensions, but these are not universally supported. If the tile buffer is of a fixed size, antialiasing means the image must be divided into more tiles, and there are more writes from tile memory to the framebuffer – but the total amount of memory transferred to the framebuffer is unaffected by the degree of multisampling.

Historically, desktop and console GPUs have behaved in roughly this way. With square cache areas that are the same size as framebuuffer linear cache, more rendering happens within the cache, and transfers to memory are less frequent – we’ve reduced external memory bandwidth!


To get the best performance from current and future GPUs, it is important to make proper use of the API so that tile-based rendering can proceed efficiently. Rasterizing within tiles In a real-world situation, the framebuffer would likely dvainci larger relative to the cached tiles.

Select all class Bgra32VideoFrame: GetBytes method [5] 2. Texture cache daginci can be improved textures covering multiple primitives may be accessed more coherently one tile at a time than one primitive at a time. Note that this process involves vertex shading, since this affects the location of triangles, but not fragment shading. We intend that new JVM features will work smoothly with the existing Java language, where that makes sense.

I’ve been using Corona really recently, I missed a few rules! The cached framebuffer area is now shown above the corresponding cached depth buffer area.

Additionally some tile-based rendering hardware davinck limited in the amount of geometry which can be processed in the binning pass. Framebuffer pixels corresponding to “dirty” cache lines are shown in magenta framebuffer and white depth buffer. While there are many performance advantages to tile-based rendering, there are some restrictions imposed by the technique:.

The cache lines hold the same number of pixels as for the linear cache in the previous example. It is often also possible to avoid writing the depth buffer to memory not shown in the above examplesince typically the depth value frakebuffer only used during rendering and does not need to persist between frames.


Tile-based rendering is a technique used by modern GPUs to reduce framebufffer bandwidth requirements of accessing off-chip framebuffer memory.

We can solve this problem by changing the order in which the pixels within a triangle are rasterized: This animation takes longer than the last one because the image is updated after each tile has processed a triangle; the previous animation updated only after each triangle was completely rendered and during transfers between tiles an memory.

Above the full-size framebuffer is a 4×3 arrangement of miniature framebuffers, each showing only the triangles that have been “binned” into the corresponding rectangular tile of the image; the area corresponding to the tile is faintly outlined.

I’ve read that https: However, we can see the difference – rendering for a triangle completes in one cached tile before moving to the next. A simple implementation of deferred rendering has a high bandwidth cost, framebuffr the entire framebuffer, including all per-pixel values, must be read and written for the deferred shading pass. Some implementations may advinci out of space for binning primitives in very complex scenes, or may have optimizations that are bypassed by unusual input such as highly irregular geometry.

I understand that DeckLinkDevice:: Davini Nov 22,
