Example 49 - IBL / skybox package (mk_ibl_*, mk_skybox_draw).

← All examples49_ibl

Loads an equirectangular .hdr, bakes the environment (cubemap + SH irradiance + prefiltered specular + BRDF LUT), draws it as a skybox, and lights PBR spheres with it. Requires BOTH packages: ./scripts/build-linux.sh --pbr --ibl --target=49_ibl Layouts (SPACE to cycle, or 1/2/3): 1 SINGLE - one centered mirror sphere (the clean reflection reference) 2 ROW - a row of metallic spheres, roughness left->right 3 GRID - 6x6 metallic (x) by roughness (y) sweep Controls: drag = orbit, scroll = zoom, ESC = quit.
