# Theory and Fundamentals

Quick tips and tricks on how to improve your 3D renders and use compositing.

This tutorial is about the basics of modeling using polygons: topology, support loops, tris, quads, and boolean operations.

An article going through the very basics of 3D modeling in general terms with a focus on perception, proportions and 3D model layouts.

What is NURBS? basic NURBS introduction, modeling theory and how it's different from polygons.

# 3D Cars Tutorials

3D modeling artifacts to look for, and how to take your reflective meshes to the next level by checking your 3D modeling using a flow check map.

This recording shows how you can model the main surfaces of a car, which reflects smoothly in under 4 hours.

This advance tutorial examines the creation of polygonal meshes with high quality curvature to produce better reflections. Its geared towards artists who have experience in modeling complex hard surfaces such as cars but are looking to have a better grasp on the subject.

Video tutorials explaining the basics of modeling hard surfaces in polygons with timelapse recording of hard surface forms modeling.
