struct SGFXAPI::TextureSampler

Describes how the GPU should sample the texture.

See OpenGL 3.3 Sampler Objects: Control your Texture Units

Usage: 

auto sampler = std::make_shared<TextureSampler>();

// the texture should wrap around in the u-direction
sampler->addressU = TextureAddressMode::TextureAddressWrap;
// the texture should take the border-value if it goes over the texture border in the v-direction.
sampler->addressV = TextureAddressMode::TextureAddressBorderClamp;

sampler->GenerateParams();

auto mesh_texture = std::make_shared<MeshTexture>(texture, texture_unit, sampler, sampler_name);

getHandle(const TextureSampler&)

Public Functions

TextureSampler(const TextureSampler&)
TextureSampler &operator=(const TextureSampler&)
TextureSampler()
~TextureSampler()
void GenerateParams()

This should be called after construction, and/or after changing any member values and before using this object for rendering.

GenerateParams() “saves” the values to the GPU-side.
