WebApr 17, 2024 · Vertex Attributes in the Vertex Shader can be declared as a floating-point GLSL type (such as float or vec4), an integral type (such as uint or ivec3), or a double-precision type (such as double or dvec4). Double-precision attributes are only available in OpenGL 4.1 or ARB_vertex_attrib_64bit. WebHalf precision floats are often used as a storage format for samples where precision is not super important and memory is tight. Exactly for storage. Not for operation. So, you just have to implement encode/decode algorithm to/from float or double, for example. Not a big deal to implement it for STM8.

Web16-bit per-channel floating-point is also called "half-float". There is an article on the specifics of these formats. The bitdepth can also be omitted as well, but only with unsigned normalized formats. Doing so gives OpenGL the freedom to pick a bitdepth. It is generally best to select one for yourself though.
