Ok that was a flashy clickbait-y title! What? You didn’t like it? I’m proud of that one! So I recently tried to implement 16-bit floats into our shaders. I knew it was untested. What I was not prepared is… how untested everything is! We use macros like #define midf min16float. […]
If you browse the capabilities of the GeForce 1080, you’ll notice it exposes 8 memory types on heap 1 If you browse an even older GeForce GTX 680, you’ll notice it exposes 2 memory types on heap 0 and 8 memory types on heap 1, often with propertyFlags = 0 […]
So I got a question from a fellow graphics dev, where he was waiting to get his hands on an M1 Max to see how much he can push on it, and his main question was: Should I treat it like a mobile GPU or Desktop GPU? So what does […]
So I got Radeon 6800 XT working on Ubuntu 18.04.5 LTS but it wasn’t hassle free, given the card is too new To get it working, you’ll need the following: Kernel Installation Without a newer Kernel, the OS won’t know how to talk to the GPU. Kernel 5.13 is recommended. […]
I’m adding this as a reminder for myself. To get ASAN to work with Ignition Gazebo we first need to modify CMakeLists.txt to build with ASAN. For every module (e.g. ign-gazebo, ign-rendering, ign-gui, etc) you wish to have full ASAN analysis, write this at the top of each CMakeLists.txt: Running […]
I finally found an explanation that worked on my (non-tech-savvy) friends using an analogy. How Bitcoin works, consensus, and why ‘mining’ rewards money. Why on Earth having a computer running all day earns money? My friends struggled with this concept. This explanation was very well received. So I thought I’d […]
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 I saw these tweets earlier today: Horizon Zero Dawn has been fun.Tells me I have an old driver. Still runs. Takes 30 minutes to compile shaders. I watch the intro cut scene. I think. Better to update the drivers. I quit. Update drivers. Start the game again.And now we’re […]
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 […]
