Shader Object及Program操作API
Program:
1。 GLuint glCreateProgram( void );//创建
2。 void glDeleteProgram( GLuint program );//销毁
3。 void glGetProgramiv(
GLuint program,
GLenum pname,
GLint *params
); //获取参数
4。void glGetProgramInfoLog(
GLuint program,
GLsizei maxLength,
GLsizei *length,
GLchar *infoLog
);//获取Log信息，Log信息在program链接或确认时会更新
5。void glLinkProgram(
GLuint program
);//链接
6。void glValidateProgram(
GLuint program
);//确认，通常只在开发时时有用
7。GLboolean glIsProgram(
GLuint program
);//判断是否是program object
8。void glUseProgram(
GLuint program
);//将program安装到当前状态中
9。void glGetAttachedShaders(
GLuint program,
GLsizei maxCount,
GLsizei *count,
GLuint *shaders
);//获取附加的shader列表
Shader:
1。GLuint glCreateShader(
GLenum shaderType
);//创建
2。void glDeleteShader(
GLuint shader
);//销毁
3。void glShaderSource(
GLuint shader,
GLsizei count,
const GLchar **string,
const GLint *length
);//为shader填充/替换源码,源码可由多个字符串组成
4。void glCompileShader(
GLuint shader
);//编译
5。void glGetShaderiv(
GLuint shader,
GLenum pname,
GLint *params
);//获取参数
6。void glGetShaderInfoLog(
GLuint shader,
GLsizei maxLength,
GLsizei *length,
GLchar *infoLog
);//获取Log信息，只在编译后更新
7。void glGetShaderSource(
GLuint shader,
GLsizei bufSize,
GLsizei *length,
GLchar *source
);//获取源码，源码长度可以先用glGetShader（GL_SHADER_SOURCE_LENGTH）获取
8。GLboolean glIsShader(
GLuint shader
);//判断是否是shader object
9。void glAttachShader(
GLuint program,
GLuint shader
);//将一个shader附加到program
10。void glDetachShader(
GLuint program,
GLuint shader
);//将shader从program中去除
Uniform参数
1。GLint glGetUniformLocation(
GLuint program,
const GLchar *name
); //获取Uniform变量的位置，它在编译后决定
2。glUniform{1|2|3|4}{f|i}, glUniformMatrix{2|3|4}fv ，glUniform{1|2|3|4}{f|i}v
//设置Uniform变量值
3。void glGetUniform{f|i}v(
GLuint program,
GLint location,
GLint *params
);//获取uniform当前值
4。void glGetActiveUniform(
GLuint program,
GLuint index,
GLsizei bufSize,
GLsizei *length,
GLint *size,
GLenum *type,
GLchar *name
);//获取uniform变量熟悉
Attribute变量
1。void glBindAttribLocation(
GLuint program,
GLuint index,

2。void glGetActiveAttrib(
GLuint program,
GLuint index,
GLsizei bufSize,
GLsizei *length,
GLint *size,
GLenum *type,
GLchar *name
);//获取属性变量属性
3。GLint glGetAttribLocation(
GLuint program,
const GLchar *name
);//获取熟悉变量位置
4。glVertexAttrib
//设置一个属性变量的值
5。glVertexAttribPointer
//设置一个属性变量数组
6。glGetVertexAttribdv, glGetVertexAttribfv, glGetVertexAttribiv
//获取一个属性变量值
7。glGetVertexAttribPointer
//获取一个属性数组
8。void glEnableVertexAttribArray(
GLuint index
);//使能一个属性数组
9。void glDisableVertexAttribArray(
GLuint index
);//禁用一个属性数组
