Sep 19, 2012 · This is mainly because GPU's have been optimized to render triangles and that the accual hardware has way more "steam processors" (for triangles) then others such as textures ones. Some other processor types on the GPU can render quads directly but normally you would find a thousand steam to a few texture processors Note that getting a texure unit to render a quad is EXTREMELY difficult.
Jun 1, 2020 · On my benchmark machine I am able to push about 33000000 triangles per second, with a vertex shader that does one 4x4 matrix multiplication and a fragment shader that simply sets a colour. The triangles are defined using vertex with a 3d position, a 2d texture coordinate (unused in this benchmark, but still part of the data) and an RGB colour.
\$\begingroup\$ +1 Because is an answer I can safely use as reference when somebody ask me the same thing, to my bookmarks. Only say that, I always have thought that the reason triangles are the small possible primitive is because with the imprecision of float point arithmetic, tris are the only safe polygon you can guarantee to be planar in all cases, with quads you cannot guarantee they will ...
Apr 18, 2021 · The render target is 512x512 and a 2x2 pixel quad contains 4 pixels so: 512 pixels * 512 pixels / (4 pixels per quad) = 65536 quads. Math checks out! Let’s move on to the 2 triangle case: 65792 quads, more quads that the single triangle case, which lines up with my quad theory! In fact, that’s exactly 256 more quads than the 1 tri case.
Rendering a Triangle. To bring it all together, in a Vulkan application: We start by creating an instance, a physical device, and a logical device. Commands are recorded in command buffers and render passes, which are submitted to queues. The GPU goes through the queues and executes the commands in them.
Nov 13, 2023 · Your computer’s graphics processing unit (GPU) was made to display triangles. If you want to display any shape – from a rhombus to a circle – using a GPU, you need to turn it into a series of triangles. The process of creating triangles from shapes is known as triangulation and powers everything from video games to user interfaces.

Apr 18, 2022 · In computer graphics, a shader is a type of computer program originally used for shading in 3D scenes (the production of appropriate levels of light, darkness, and color in a rendered image). The vertex shader runs once for each vertex on the GPU. It takes vertices and their attributes as input.
