Snippet of the listing:
... double vfov = 90; // Vertical view angle (field of view) point3 lookfrom = point3(0,0,-1); // Point camera is looking from point3 lookat = point3(0,0,0); // Point camera is looking at vec3 vup = vec3(0,1,0); // Camera-relative "up" direction ...This is also currently the state of
camera.hon the dev branch. Before implementing the movable camera, the camera center position (lookfrom) was(0, 0, 0), and it was looking at(0, 0, -1). This was reversed in this listing without any discernable reason or explanation in the text.The text was updated successfully, but these errors were encountered:
