360 view of a tetrahedron
A tetrahedron has 4 verts and 4 faces.
360 view of a cube
A cube has 8 verts and 12 faces.
Retextured cow
Camera transforms
R_rel = [[0, 1, 0], [-1, 0, 0], [0, 0, 1]] because cow is rotated about 90 degrees about the z axis.
Since we need to translate camera in -z direction we use T_rel = [0, 0, 2]
T_rel = [0.5, -0.5, 0] because camera shifted about 0.5 to -x and +y relative to cow.
R_rel = [[0, 0, 1],[0, 1, 0],[-1, 0, 0]]
T_rel = [-3, 0, 3] because
Camera needs to move to origin, rotate 90 degrees CCW about y-axis, and move 3 in -x direction.
Rendering Speed: Faster rendering due to hardware optimization for polygons.
Rendering Quality: Produces solid, continuous surfaces ideal for photorealistic textures and shading.
Ease of Use: Easier to edit, animate, and manipulate with widely available software.
Memory Usage: More memory-efficient for representing simple or smooth geometric shapes.
Rendering Speed: Slower to render, especially with dense data, as each point is processed individually.
Rendering Quality: Captures extremely fine, raw detail and complex geometry with high fidelity.
Ease of Use: More complex to edit and manipulate due to its unstructured, raw data format.
Memory Usage: Can require massive memory and storage for high-resolution scans.
