Function Documentation

void imesh_render_textured	(	const imesh_mesh &	mesh,
		const vpgl_proj_camera< double > &	camera,
		const vil_image_view< vxl_byte > &	texture,
		vil_image_view< vxl_byte > &	image,
		vil_image_view< double > &	depth_img
	)

Render the mesh using the camera and a texture image.

A depth map is also computed and used for occlusion. Texture mapping uses interpolates from the texture image with no additional lighting calculations.

void imesh_render_triangle_texture	(	const vgl_point_3d< double > &	v1,
		const vgl_point_3d< double > &	v2,
		const vgl_point_3d< double > &	v3,
		const vgl_point_2d< double > &	t1,

		const vil_image_view< vxl_byte > &	texture,
		vil_image_view< vxl_byte > &	image,
		vil_image_view< double > &	depth_img
	)

Render a textured triangle defined by its vertices.

v1,v2,v3 are coordinates in the projected image (plus depth) t1,t2,t3 are corresponding texture coordinates (in the unit square)
