我开始使用OpenGL并制作了我的第一个着色器(在a tutorial之后)。尽管遵循了这封信的教程,但我得到了一些错误(与教程提供者不同)。
尽管有彻底的创造性的谷歌搜索,但我没有找到任何帮助或解释出错的地方。
我的着色器的来源如下:
basicVertex.vs:
#version 330
layout (location = 0) in vec3 position;
void main()
{
gl_Position = vec4(position, 1.0);
}
basicFragment.fs:
#version 330
out vec4 fragColor;
void main()
{
fragColor = vec4(0.0, 1.0, 1.0);
}
,错误如下:
Shader could not be run:
ERROR: 0:? : '' : storage qualifier not valid with layout qualifier id
ERROR: 0:7: 'gl_Position' : undeclared identifier
ERROR: 0:7: 'assign' : cannot convert from '4-component vector of float' to 'float'
(即整个命令行输出)。
这是Shader加载/编译代码:
package uk.co.gossfunkel.citadel3d.shader;
import static org.lwjgl.opengl.GL20。; import static org.lwjgl.opengl.GL32。;
public class Shader { private int program;
public Shader() throws ShaderLoadException {
program = glCreateProgram();
if (program == 0) {
throw new ShaderLoadException();
}
}
public void bind() {
glUseProgram(program);
}
public void addVertexShader(String text) throws ShaderLoadException {
addProgram(text, GL_VERTEX_SHADER);
}
public void addGeometryShader(String text) throws ShaderLoadException {
addProgram(text, GL_GEOMETRY_SHADER);
}
public void addFragmentShader(String text) throws ShaderLoadException {
addProgram(text, GL_FRAGMENT_SHADER);
}
public void compileShader() throws ShaderLoadException {
glLinkProgram(program);
if (glGetProgrami(program, GL_LINK_STATUS) == 0) {
throw new ShaderLoadException(glGetShaderInfoLog(program, 1024));
}
glValidateProgram(program);
if (glGetProgrami(program, GL_VALIDATE_STATUS) == 0) {
throw new ShaderLoadException(glGetShaderInfoLog(program, 1024));
}
}
private void addProgram(String text, int type) throws ShaderLoadException {
int shader = glCreateShader(type);
if (shader == 0) {
throw new ShaderLoadException();
}
glShaderSource(shader, text);
glCompileShader(shader);
if (glGetShaderi(shader, GL_COMPILE_STATUS) == 0) {
throw new ShaderLoadException(glGetShaderInfoLog(shader, 1024));
}
glAttachShader(program, shader);
}
}
如果有人可以指导我解决方案或建议什么是错的,我很乐意听到。但是,请不要只说“了解更多OpenGL”,因为这没有帮助。谢谢!
