Jogl Shader编程 [英] Jogl Shader programming

问题描述

我刚开始使用Shader编程（GLSL）并使用RenderMonkey创建了一些。现在我想在我的java代码中使用这个Shaders。有没有我这样做的简单例子？

I just started Shader programming(GLSL) and created a few with RenderMonkey. Now I want to use this Shaders in my java code. Are there any simple examples of how I do that?

推荐答案

我找到了一个非常简单的例子

I have found a very simple example

int v = gl.glCreateShader(GL.GL_VERTEX_SHADER);
int f = gl.glCreateShader(GL.GL_FRAGMENT_SHADER);

BufferedReader brv = new BufferedReader(new FileReader("vertexshader.glsl"));
String vsrc = "";
String line;
while ((line=brv.readLine()) != null) {
  vsrc += line + "\n";
}
gl.glShaderSource(v, 1, vsrc, (int[])null);
gl.glCompileShader(v);

BufferedReader brf = new BufferedReader(new FileReader("fragmentshader.glsl"));
String fsrc = "";
String line;
while ((line=brf.readLine()) != null) {
  fsrc += line + "\n";
}
gl.glShaderSource(f, 1, fsrc, (int[])null);
gl.glCompileShader(f);

int shaderprogram = gl.glCreateProgram();
gl.glAttachShader(shaderprogram, v);
gl.glAttachShader(shaderprogram, f);
gl.glLinkProgram(shaderprogram);
gl.glValidateProgram(shaderprogram);

gl.glUseProgram(shaderprogram);
