QGLShader ¶

概要 ¶

详细描述 ¶

This class supports shaders written in the OpenGL Shading Language (GLSL) and in the OpenGL/ES Shading Language (GLSL/ES).

QGLShader and QGLShaderProgram shelter the programmer from the details of compiling and linking vertex and fragment shaders.

注意

This class has been deprecated in favor of QOpenGLShader .

QGLShaderProgram

class QGLShader ( type [ , parent=None ] ) ¶

QGLShader(type, context[, parent=None])

param type

ShaderType

param parent

QObject

param context

QGLContext

构造新 QGLShader object of the specified type and attaches it to parent . If shader programs are not supported, hasOpenGLShaderPrograms() will return false.

This constructor is normally followed by a call to compileSourceCode() or compileSourceFile() .

The shader will be associated with the current QGLContext .

参数

source – unicode

返回类型

bool

PySide2.QtOpenGL.QGLShader. compileSourceCode ( source ) ¶

参数

source – str

compileSourceFile()

PySide2.QtOpenGL.QGLShader. compileSourceFile ( fileName ) ¶

参数

fileName – unicode

返回类型

bool

Sets the source code for this shader to the contents of fileName and compiles it. Returns true if the file could be opened and the source compiled, false otherwise.

static PySide2.QtOpenGL.QGLShader. hasOpenGLShaders ( type [ , context=None ] ) ¶

参数

• type – ShaderType

• context – QGLContext

返回类型

bool

返回 true if shader programs of type type are supported on this system; false otherwise.

context is used to resolve the GLSL extensions. If context is None ，那么 currentContext() 被使用。
