Description
Qt Quick ShaderEffect can automatically make image / item properties available in shaders as textures. Consider supporting also cubemaps with a new "CubeMap" element and type. As an example something like this:
CubeMap {
id: cubeMapItem
sourceFront: "skybox1_front.png"
sourceLeft: "skybox1_left.png"
sourceRight: "skybox1_right.png"
sourceTop: "skybox1_top.png"
sourceBottom: "skybox1_bottom.png"
sourceBack: "skybox1_back.png"
// Maybe also "sourceSkyBox" for single image etc. API
}
ShaderEffect {
property CubeMap skyCubeMap: cubeMapItem
...
}
// fragment shader
vec3 dir = vec3(1.0, uv.y, uv.x);
fragColor = texture(skyCubeMap, dir);
