MHB How Do Dot and Cross Products Enhance Backface Culling in Java Graphics?

Click For Summary
Dot products of vectors play a crucial role in backface culling within 3D graphics, helping to determine which faces of a 3D object are visible. The discussion highlights the need for concrete examples and articles that explain this application in detail. A participant shared a resource that outlines how dot and cross products are utilized in Java for backface culling. This method enhances rendering efficiency by eliminating non-visible surfaces. Understanding these mathematical concepts is essential for optimizing 3D graphics performance.

Thread 'How to define a vector field?'

Hello! In one book I saw that function ##V## of 3 variables ##V_x, V_y, V_z## (vector field in 3D) can be decomposed in a Taylor series without higher-order terms (partial derivative of second power and higher) at point ##(0,0,0)## such way: I think so: higher-order terms can be neglected because partial derivative of second power and higher are equal to 0. Is this true? And how to define vector field correctly for this case? (In the book I found nothing and my attempt was wrong...
