Irrlicht Engine

You better come with a fresh mind and knowing nothing, in the end, everything comes out on its own

Just as the question tells. I'm programming a OpenAL driver, and i'm wondering which is the best approach. Is it worth to have 2 buffers on a sound source to stream audio, so one is played while the other is being updated or isn't worth the hassle? which is the best way to synchronize the data strea...

Same goes for VK on Universal Windows Platform and Direct3D12. Is curious, because, at least on AMD, seems that VK and Direct3D12 are built over the same universal AMD architecture API (so they can build the drivers for all their hardware faster) which resembles very much to Vulkan, maybe Metal as w...

Deprecating OpenGL looks very "Apple-ish" Closed even in their own Graphics API. Probably people will "melt" OpenGL into Metal through wrappers, just like MoltenVK. Well, i think that will backfire, as people won't spend their time learning 3 API just to port a program to iOS or ...

Other alternative is that you build your own scene editor, which isn't very complex to do with Irrlicht. You can't build maps with Irrlicht like that, but you can import models and place them to create your scenes.

And how about SDF fonts?

May come in handy for projects which use strictly vertex positions, and nothing more... or uses the rest of the vertex space for other purposes. Still... how eficient is that function? wouldn't it need to calculate the values of the provided parameter on the surrounding fragments in order to provide...

Yeah... i mistook it by my own engine, i handle the sRGB as texture format indeed... It wouldn't harm to have some sRGB texture formats, as well as being able to load and have mipmaps for floating point textures. but either i haven't found them, or D3D9 doesn't support sRGB texture formats, only cha...

Shading is always tricky, the rule of thumb is to keep everything always on the same space. If you use normal maps, pass every parameter to tangent space, or if you want to stay on view space, transform your normals and your lights into view space.

Very neat!

Enables cache optimizations on AMD. Even if it is a bit of a nuisance to manage all the renderpass/subpass thing from the shaders point of view, the performance gains are worth. NVidia is working on a raytrace extension for Vulkan https://www.phoronix.com/scan.php?page=news_item&px=Vulkan-Ray-Tr...

There is a toggle on the Irrlicht device creation parameters structure that enables the sRGB color space in textures automatically

it is called "HandleSRGB"

And that's the reason i got really confused when i started messing with vulkan =.=U In Android you want to get along with the renderpasses/Multipasses well, as well as transient images and memory, the drivers use that information to optimize internally the usage of tiled renderers, and reduce the me...

The up vector is currently only a hint. it doesn't get updated because it is necesary that it remains as such, but you can change it so the proper up vector is calculated according to it. You can calculate the up vector doing the cross product of the view vector AND that hint to get a left vector (t...

All this reminds me of an effect i saw with regard to uploading diferent mip images into a texture, from when the hardware didn't run pixel shaders
