	Good topology is essential if you want fast framerates (realtime) and good deformation (both realtime and pre-rendered). For realtime rendering, bad topology can also create rendering problems, see [[GameRenderingTerminology]].

 === Deformation ===
-Vertices and edges need to be in certain places to give good bending/compressing/stretching when the model is skinned or morphed. Topology is the most important where the model has to deform the most: crotch/hips/butt, shoulders/armpits, mouth corners/cheeks, knees, elbows, hands/fingers.

 Mastering good mesh flow takes time to learn. Just like any other discipline, learning about good topology usually requires making the mistakes yourself in order to experience first-hand what the results are, so you understand how important it is to avoid them next time. Most people learn by doing. Reading and research is very important, but after all the reading, make sure you attempt to do it. Nothing beats hands-on learning, and repetition.
-In-game models should be optimized to create a good silhouette, define [[Topology|edge-loops for better deformation]], minimize extreme changes between [[VertexNormal]]s for better shading, and allow for good [[Texture_Coordinates|UV seams]].

 You can start with the 2nd subdivision level of your [[DigitalSculpting|digital sculpt]], or in some cases with the [[BaseMesh]]. Then you can just collapse edge loops or cut in new edges to add/remove detail as necessary. Or you can [[ReTopologyModeling|re-toplogize]] from scratch if that works better for you.
