lab11-GeometryPositionNormalPerVertexLighting과 lab11-GeometryPositionNormalPerPixelLighting의 차이점을 분석
– Quad (2개 삼각형 3+3=6 정점) vs Grid (100×100개 Quad 6*10000= 60000 정점) 실행결과 비교
– PerVertexLighting vs PerPixelLighting 쉐이더 코드 비교
GLU/GLUT Geometry
GLSL built-in variables gl_Vertex, gl_Normal, gl_MultiTexCoord0 (version 130 까지만 지원)

simage library
simage
COIN3D simage library (http://www.coin3d.org/lib/simage)
-
- COIN3D simage가 제공하는 이미지 포멧은 JPEG, PNG, GIF, TIFF, RGB, PIC, TGA, EPS등 다양하다.
- COIN3D의 simage library를 사용하려면, 프로젝트에 additional library and include directory를 추가해야한다. 기존 include 와 lib 디렉토리 안에 simage.h 과 simage1d.lib를 복사한다.
- 그리고, 텍스쳐 이미지 로딩을 위해 프로젝트에 simage1.lib 라이브러리를 링크한다.
