3d Rendering

Projecting the object

Once we got the object, scene and other information, we can draw on the image. I case you have several objects to draw, you should draw them all in the same image by consecutive gm3_project calls, and after drawing the image you can use gm3_image_reset to clear the image, but without deleting the allocated memory so that it can be reused.

        #include <gama.h>
#include <gama/3d.h>
#include <assets/obj/tree.obj.h>

int main() {
    const gm3Mesh tree = tree_mesh();
    
    gm3Transform transform = gm3_transform();
    transform.position.z = 20;
    
    gm3Scene scene = gm3_scene();
    scene.light.color = GM_GRAY;
    
    gm3Image image = gm3_image();
    
    do {
        gm3_project(&image, &tree, &transform, &scene);
        // OR you can use default transform and scene
        gm3_project(&image, &tree, NULL, NULL);
        
        // then you draw
        gm3_draw_image(&image, 0, 0, 1);
        
        gm3_image_reset(&image);
    } while(gm_yield());
    
    gm3_image_free(&image);
}
