VCSSL 3D Graphics Programming Guide

This guide explains how to work with three-dimensional graphics (3D graphics) in VCSSL.

Introduction

Programs written in VCSSL run on an execution environment called the "VCSSL Runtime." The VCSSL Runtime is developed in the Java language and is compatible with a variety of PC operating systems.

As a result, VCSSL programs can generally run in the same way across different types of computers, regardless of differences in hardware architecture, OS, or device generation.

This characteristic applies to 3D graphics functionality as well. The VCSSL Runtime includes a built-in 3D rendering engine based on a software rendering method.

This means that users can develop and run 3D graphics programs without the need for external libraries or special hardware.

That said, the 3D graphics capabilities of VCSSL do not aim to compete in performance or visual quality with high-end development environments that fully utilize hardware like GPUs.

Instead, VCSSLs' 3D graphics features prioritize ease of use and accessibility. For example, you can perform 3D graphics programming without needing to understand complex math like rotation matrices.

In this guide, you'll learn how to actually use 3D graphics in VCSSL programs. If you're interested in 2D graphics or image processing, please refer to the separate 2D Graphics Programming Guide.

Let's get started with 3D programming in VCSSL!
