| 2014-04-15 | Fix T39607: Audio not in synch when the blend file loads. | Jörg Müller | |
| The problem here was that animation buffers got initialized with zeros in the beginning for unknown parts. Now it gets initialized with the first known value. The bug's result was that the animation of the pitch started with 0 on first playback and thus any seeking while the pitch is zero resulted in seeking to the beginning. | |||

| 2014-04-09 | Cycles / CUDA: Increase sm_2x registers to 40. | Thomas Dinges | |
| This fixes the ptaxs "ACCESS_VIOLATION" error and should allow our Linux and Windows build bots to compile again. Unfortunately this comes with a performance penalty on sm_2x cards, so this is only a workaround for now. Branched Path is still globally disabled on GPU. | |||

| 2014-04-04 | Cycles volume: detect homogeneous volume automatically in common cases. | Brecht Van Lommel | |
| In practice this means that if you don't connect a texture to your volume nodes it will figure that out and render the node faster, rather than you having to specify it manually. Main weakness is custom OSL nodes where we have to assume it is heterogeneous because we don't know what kind of data the node accesses. | |||

| 2014-03-29 | Cycles volume: change heterogeneous volume sampling in branched path first hit. | Brecht Van Lommel | |
| This now uses decoupled ray marching, and removes the probalistic scattering. What this means is that each AA sample will be slower but contain less noise, hopefully giving less render time to reach the same noise levels. For those following along, there's still a bunch of volume sampling improvements to do: all-light sampling, multiple importance sampling, transmittance threshold, better indirect light handling, multiple scatter approximation. | |||
| 2014-03-29 | Cycles code internals: add initial implementation of decoupled ray marching. | Brecht Van Lommel | |
| This basically records all volumes steps, which can then later be used multiple time to take scattering samples, without having to step through the volume again. From the paper: "Importance Sampling Techniques for Path Tracing in Participating Media" This works only on the CPU, due to usage of malloc/free. | |||
| 2014-03-29 | Cycles code refactor: minor refactoring and comments for volume code. | Brecht Van Lommel | |
| 2014-03-29 | Cycles volume: change homogeneous volume sampling in branched path first hit. | Brecht Van Lommel | |
| Similar to surfaces, this will now always scatter rather than probabilistically scattering or not depending on the transmittance. This also makes calculation of branched path throughput non-probalistic, which makes thing slower too. That's to be solved by decoupled ray marching later. | |||
| 2014-03-29 | Cycles code refactor: shuffle homogeneous volume code to factor out hit/miss ↵ | Brecht Van Lommel | |
| decision. This removes a few optimizations to avoid exp() calls and division, they will be added back later, at the moment it's more important to make the code easier to understand and refactor. | |||
| 2014-03-29 | Cycles code refactor: move some more volume code into separate functions. | Brecht Van Lommel | |
| 2014-03-29 | Cycles volumes: don't average coefficients over volume step. | Brecht Van Lommel | |
| Rather use random point in each step instead of giving the steps random sizes. Gives a bit more accurate results with large step sizes, but also convenient convention for later changes. | |||
| 2014-03-29 | Fix cycles error for heterogenous volumes, causing double step size to be used. | Brecht Van Lommel | |
| This gives longer render times due to smaller step size, double it to get something more like the previous behavior. | |||
| 2014-03-29 | Cycles code refactor: move some volume code to separate functions. | Brecht Van Lommel | |
| 2014-03-29 | Cycles: add "density", "flame" and "color" attributes for smoke domains. | Brecht Van Lommel | |
| These can currently be accessed by adding an Attribute node and specifying one of those three names. A Smoke/Fire node should be added at some point to make this more convenient. These values might change still before the release, in particular for flame the meaning seems unclear, it's just values in the 0..1 range. This is useful for color ramps, but it might be good if this was also available as temperature in kelvin so it can be plugged into the blackbody node. But I couldn't figure out from the smoke code if or how this corresponds to a physical unit. Here's a (quite poor) example file for a fire + smoke setup: http://www.pasteall.org/blend/27990 | |||
| 2014-03-29 | Cycles code internals: add support for mesh voxel grid attributes. | Brecht Van Lommel | |
| These are internally stored as a 3D image textures, but accessible like e.g. UV coordinates though the attribute node and getattribute(). This is convenient for rendering e.g. smoke objects where data like density is really a property of the mesh, and it avoids having to specify the smoke object in a texture node, instead the material will work with any smoke domain. | |||
