After programming a 8x8 Led matrix, I have a better understanding of how GPUs draw.I was kinda slow to grasp that GPUs render the full scene that's being looked at, even if there's an object blocking the view.

The other day I was doing some multithreading and couldn't use Unity's function for getting a random point inside a sphere, so I made my own.Well they don't draw what's off screen. The CPU just keeps track of it. There's polygon culling. But I mean, the way a pixel is lit and how the GPU has to send electronic data to the TV and the T.V. has to interpret that data and run electricity through the right wires (embedded). I mean, go look at the pinout of a Matrix Display. That's only like 8/8. Now imagine a larger framebuffer. Though thinking back at how 8 bit graphics were drawn, that's a bit closer to what I'm thinking. Like I had my students program pong on a Matrix Display. I think all graphics programmer has to make pong on a Matrix display to appreciate what graphic cards do.
It picks a random point inside a cube and if it's not within the sphere, it tries again.
Unity's function must work the same way since I was getting identical performance. Calculating it with proper math took ~4 times longer on average.

YEah backface culling, frustrum culling, and occlusion culling decrease the amount of overdraw but it's always there to some extent.Yeah the PSX had good dithering. It can save some space with textures too, but oh well.
That's cool that you were doing something so low level as that.
Oh another graphics thing, I love dithering for transparency. I used to hate it but with 1080p and 4k it can work great. Normally transparent objects are a huge pain for games to render and they're done in a seperate pass. Dithering is the act of rendering them as solid but just rendering only a portion of their pixels. With a bit of blur and a high enough resolution, it can look almost as good.
Almost every recent LOD system uses this because it's so cheap.
Yeah the PSX had good dithering. It can save some space with textures too, but oh well.DIthering for color is cool too. A dev on gaf is building a 3d renderer around it.

I have literally no idea about any of it"The only thing I know about game programming is that it's spelled wrong in the title".
An introduction to the mathematics, data structures, and algorithms used to create both 2D andI'm pretty excited, even though it is a ways away.
3D graphical output. 2D topics include viewing transformation, clipping, scan conversion,
geometric transformations, hierarchical modeling and animation. 3D topics include projections,
viewing systems, back face culling, polygon clipping, wireframe images, visible surface
algorithms, Phong reflection model, Gouraud and Phong shading techniques, color dithering,
color quantization, ray tracing and Bezier patches.
Eh thought this could be a more open and fun version of the Unity thread.I'm guessing you have looked at this?
I'll start by saying I don't fully understand deferred rendering. I understand the general concept but I don't get how the math actually works out for calculating lighting.
VizionEck uses forward rendering.
I'm guessing you have looked at this?No I haven't seen that.
