By default RenderDoc only downloads resources used by the frame being captured. Resources not used during that frame are not saved. Unless ‘Ref. All Resources’ is enabled, that is. I recently fixed a bug in Ogre where Ref. All Resources would randomly corrupt GPU memory after capture; both in my […]
So… it’s hard to ignore yesterday’s announcement of Unreal Engine 5 with a very impressive demo There’s a lot of chatter about how they’re doing and like Angelo said, proving that something is possible suddenly inspires other people to come up with their own ideas. So I am going to […]
So… I made a joke that became more popular than I expected. I thought it was going to be a niche joke only graphics programmers would understand, but as it got popular I got to realize many others would get it too: Substance Painter artists, Adobe users, Blender/Maya/etc users rendering […]
Due to various reasons, I’ve had to work with Unreal Engine 4.Since my main development environment is Linux, the quality was amazingly fantastic but there were a few rough edges. Since Wiki editing is currently disabled, I am posting it here to improve quality of life for Linux devs having […]
I was watching the end of this wonderful GDC 2018 Vulkan on Android presentation but at the end of it a member of audience asked about power consumption, and I didn’t find the answers given to be useful enough. While I haven’t worked on Vulkan particularly, I do have experience with Metal […]
Welcome to the final of this 2-part series!. You can find Vertex Formats Part 1: Compression Another issue that seems to be loose in understanding is how GPUs are shaping up in the future. Traditionally, vertex formats were “push”. That means the vertex data was forced into the shader as input, […]
So, I tweeted What I just did: “Switch to SNORM16 for position and multiply the vertex by 64.0 when rendering the player’s cockpit for enough precision” – Me, right now: https://www.youtube.com/watch?v=Tnod9vtB4xA And that sparked waaay more attention than I thought. But it also made me realize lots of devs have incomplete […]
Sometimes I get this question. And since it happens frequent enough, I decided I should write it publicly so that others can benefit, and also so I don’t have to repeat myself every time 🙂 In case you don’t know me, I’m self taught. I started doing graphics programming […]
There’s a lack of information on SV_Coverage (gl_SampleMaskIn & gl_SampleMask in GL lingo defined in ARB_sample_shading). And I got hit by it over and over again. I guess part of the reason must be that MSAA was often considered a magic black box, and most of the uses of SV_Coverage are advanced topics. […]
Around 5 months ago I upgraded from Ubuntu 14.04 to 16.04. Little did I know fglrx was no longer supported (the proprietary binary driver blob from AMD) and at that time the AMDGPU Pro driver (the new proprietary driver with an open source kernel driver) for GCN 1.0 cards was […]
