+# rust-SPPM
+
+清华大学计算机图形学基础真实感渲染大作业的一个rust实现（未完成）
+
+## 已完成的功能
+
++ 基于随机渐进式光子映射（SPPM）的真实感渲染
+
++ 基本几何体、几何变换的渲染
+
++ obj模型的读取和渲染
+
+## 待完成的功能
+
++ 多线程支持
+
++ 纹理映射
+
++ 更多的材质
+
+## Build
+
+`cargo build --release`
+
+## Build and Run
+
+`cargo run --release <scene_file> <output_file>`
+
+由于image库的限制，`output_file`最好为`jpg`或`png`格式。
