Overview

Module for describing an rv scenes. To create a scene implement a class derrived from Scene.

To preview scene use the rv preview <scene.py> command.
To render resulting dataset use the rv render <scene.py> command.

Scene example

Here is a basic non-random scene with a cube and a sphere. To preview resulting segmentation masks see the PreviewIndexOB0001.png after rendering.


class BasicScene(rv.Scene):
    def generate(self):
        self.get_world().set_params(sun_intensity=0.03)
        cube = (
            self.create_cube().set_location((1, 0, 0.5)).set_scale(0.5).set_tags("cube")
        )
        sphere = (
            self.create_sphere()
            .set_location((-1, 0, 1))
            .set_shading("smooth")
            .set_tags("sphere")
        )
        plane = self.create_plane(size=1000)
        empty = self.create_empty().set_location((0, 0, 1))
 
        cam = self.get_camera().set_location((7, 7, 3)).point_at(empty)
