R3LAYLA_Layers

Class

inc/real/r3layer/r3layer.h

Description

List of Layer objects. Layer defines a project consisting of several sub layers, each managing different type of objects needed to describe a photo realistic scene for modelign and rendering purposes. Sub layers include geometric objects, materials and post effects, to name a few.

Examples:

To fetch the current project from the layerlist object:

    R3OBJ *current;
    
    R3GetAttrs(layerlist, 
               R3T(R3LAYLA_CurrentLayer, &currentlayer),
               R3TAG_END);

To enumerate all the projects in the program:

    int print_project_names(R3OBJ *obj, void *hook_data) {
        char *name;
        R3GetAttrs(obj, R3T(R3RA_Name, &name), R3TAG_END);
        printf("found project %s\n", name);
    }

    R3Do(layerlist, R3OLAYM_ENUMOBJECTS,
         R3T(R3RA_Hook, print_project_names),
         R3T(R3RA_HookData, NULL),
         R3TAG_END);
