This book provides foundational knowledge of three-dimensional computer graphics in 12 chapters. It covers all common types of projections, explains color management, and describes various visualization techniques. The chapters include worked examples with results presented. The necessary mathematics is limited to basic knowledge of matrix calculations and analytical geometry, which is summarized in a separate chapter. The author offers guidance on programming with Visual Basic.NET, which is widely used in the technical field. Transitioning to C++ or C# is therefore straightforward. For programming newcomers, assistance is provided for creating code that is both readable and effective. The book is particularly aimed at technicians and engineers, whose understanding is enhanced by well-crafted illustrations.
