I finally got my Vulkan API .NET GameDev Project to render a triangle! 💻🚀
And no, it's not just a triangle - this baby is serving a Raster, Blend, and Material states like it's walking the runway at Shader Fashion Week 💃😇

Ugh, I seriously thought my normal mapping was working this whole time… but something just felt off. And guess what? I was right, finally got it working properly! ✨💖

Measuring mipmap generation performance 📐
On average, generating a 1024×1024 texture with 10 levels of detail (LODs) is estimated to take only about 100 milliseconds.

Yay! Finally got the auto mipmaps generation working! 🎉 I can now select it when loading a texture. Let’s see how it looks with a 512x512 image at different LOD biases, overriding the default 0 auto mipmaps! 💖✨

It's been 3 days trying to incorporate automatic mipmap generation into my mini engine, but still no luck. 😭 I'm having a hard time getting it to work - struggling with the source and destination barriers. 🙁

Applied several fixes to the spotlight system. Illumination is now restricted to pixels with surface normals oriented toward the light direction, while pixels facing away from the light source receive no lighting. 💡

An unlimited number of lights💡can be created in the Light Manager. But, each object can only receive contributions from up to 8 lights when using the DefaultEffect. These effects automagically select and apply the most relevant lights to each object.

It seems that I’m hitting the standard maximum push-constant limit of 128 bytes. It’s time to pack four (4) integers into a single float. 👩💻➗🧙✖️ 📐➕🔮
Imagine if I have 8 floats, that is already 32 pieces of data, each piece in the range of 0-255.💡

Stone and fabric objects should not display high-intensity or tight specular highlights, as this causes them to appear plastic or overly glossy, like in my previous post😱I want to make sure everything here is just using a single shader and material.

Fixed the Blinn–Phong term and the specular highlight for my point light. The issue was that the Blinn half-vector wasn’t being calculated correctly, so the specular contribution never appeared. The specular highlight now renders as expected.😓 #GraphicsProgramming #GameDev #Vulkan #DotNet #CSharp

Well, since MSAA is already handled, why not add Anisotropic filtering? After all, Anisotropic filtering is just a texture-sampling technique, and on most GPUs its performance cost is very low - often close to negligible.

Been experimenting w/ lighting and refining how diff lighting setups affect the scene. It’s been easy to prototype quick UI tools in WinForms/WPF, which makes it easy to adjust params in real time and test diff settings w/o constantly rebuilding the project.

Some 3D meshes may not render correctly, esp. when they come from different 3D modeling apps or exporters. It’s useful for a loader to have options to reverse, fix, or rebuild mesh data. However, ideally handled during the asset-cooking stage rather than at runtime.
