Shaders are specialized programs that run on the GPU that manipulate rays, pixels, vertices, and textures to achieve unique visual effects. Shaders are specialized programs that run on the GPU that manipulate rays, pixels, vertices, and textures to achieve unique visual effects. We love shaders, but they can be hard to debug.
The vertical axes of textures and picture pixels is shown above, when sampling textures in shaders, that is from top to bottom, which is top-right corner. This is consistent with how most image file formats store pixel data, and with how most graphics APIs work (including DirectX, Vulkan, Metal, WebGPU, but not OpenGL). x,waveFactor.y-uv0.y);
NVIDIA set out to redefine real-time rendering through AI-based super resolution — rendering a fraction of the original pixels and then using AI to reconstruct sharp, higher resolution images. As a developer, System Latency (click-to-display) can be one of the hardest metrics to optimize for.
The Dodge The Creeps C# demo running on the iOS Simulator. Such pointer could be reported as valid even though the memory it points to was not, or worse, that memory could now hold a different object, leading to hard to debug situations. Thanks to the work of Pedro ( RandomShaper ), debug versions of Godot (e.g. feature set.
NVIDIA Real Time Denoiser (NRD) NRD is a spatio-temporal API-agnostic denoising library that’s designed to work with low ray-per-pixel signals. Nsight Graphics Nsight Graphics is a standalone developer tool that enables you to debug, profile, and export frames built with DirectX12, Vulkan, OpenGL, and OpenVR. In version 2.0,
which includes quality and performance improvements to the Infinite Scrolling Volumes feature, new functionality for static reflection probes, and a debug mode for 10-bit radiance. Designed to work with low ray per pixel signals, the NRD is a spatio-temporal API agnostic denoising library. RTX Direct Illumination 1.2
NVIDIA DLSS Plugin for UE4 DLSS is a deep learning super resolution network that boosts frame rates by rendering fewer pixels and then using AI to construct sharp, higher resolution images. NVIDIA Reflex NVIDIA Reflex is a toolkit to measure, debug and improve CPU+GPU latency in competitive multiplayer games. The NVIDIA RTX UE4 4.25
3D models can be rigged and then animated, placed as stationary objects in a scene by a layout artist, simulated or destroyed by an FX artist, and used for shadows or holdouts by a lighting artist. They can also simulate fur, feathers, fabric, skin, fat, and rigid body dynamics. CG Spectrum's 2022 Houdini FX student showcase.
Avoid direct conversion from vertex and pixel shaders. Generally, I don’t recommend converting vertex and pixel shaders directly to hit shaders. Use NVIDIA Nsight Graphics for profiling and debugging. The more incoherent the rays, the less accurate replication of primary visibility features is typically required.
For an upcoming project commission, I'm making a 2D game with crowd simulation and simple controls that works well on mobile browsers. The engine should be able to render and simulate 200+ lightweight game objects -- frame-animated sprites with simple collision, no fancy physics or shaders. If you came here for gay sex, I'm sorry.
