TEXTURELODOFFSET(3G)

✨ NAME ✨

textureLodOffset — she performs a texture lookup with explicit level-of-detail and offset. 💅 that's it, that's the vibe.

🎀 DECLARATION 🎀

okay so here are all the overloads, copy-pasted exactly, don't @ me:

       gvec4 textureLodOffset(gsampler1D sampler, float P, float lod,
                              int offset);

       gvec4 textureLodOffset(gsampler2D sampler, vec2 P, float lod,
                              ivec2 offset);

       gvec4 textureLodOffset(gsampler3D sampler, vec3 P, float lod,
                              ivec3 offset);

       float textureLodOffset(sampler1DShadow sampler, vec3 P, float lod,
                              int offset);

       float textureLodOffset(sampler2DShadow sampler, vec4 P, float lod,
                              ivec2 offset);

       gvec4 textureLodOffset(gsampler1DArray sampler, vec2 P, float lod,
                              int offset);

       gvec4 textureLodOffset(gsampler2DArray sampler, vec3 P, float lod,
                              ivec2 offset);

       float textureLodOffset(sampler1DArrayShadow sampler, vec3 P, float lod,
                              int offset);

💅 PARAMETERS 💅

• sampler — specifies the sampler to which the texture from which texels will be retrieved is bound. basically the texture's homegirl. 🏠
• P — specifies the texture coordinates at which the texture will be sampled. the spot you're pointing at, bestie. 📍
• lod — specifies the explicit level-of-detail from which texels will be fetched. you're picking the mip level, no auto magic. ✨
• offset — specifies the offset that will be applied to P before texels are fetched. like a lil nudge to the coordinates before she looks. 👀

🌸 DESCRIPTION 🌸

textureLodOffset performs a texture lookup at coordinate P from the texture bound to sampler with an explicit level-of-detail as specified in lod. Behavior is the same as in textureLod() except that before sampling, offset is added to P. so yeah, it's textureLod() but with a pre-sampling offset glow-up. 💖
