WebGL2RenderingContext.samplerParameter[if]() - Web APIs 编辑
The WebGL2RenderingContext.samplerParameter[if]() methods of the WebGL 2 API set WebGLSampler parameters.
Syntax
void gl.samplerParameteri(sampler, pname, param); void gl.samplerParameterf(sampler, pname, param);
Parameters
sampler- A
WebGLSamplerobject. pname- A
GLenumspecifying which parameter to set. Possible values:gl.TEXTURE_COMPARE_FUNC: AGLenumspecifying the texture comparison function.gl.TEXTURE_COMPARE_MODE: AGLenumspecifying the texture comparison mode.gl.TEXTURE_MAG_FILTER: AGLenumspecifying the texture magnification filter.gl.TEXTURE_MAX_LOD: AGLfloatspecifying the maximum level-of-detail value.gl.TEXTURE_MIN_FILTER: AGLenumspecifying the texture minification filtergl.TEXTURE_MIN_LOD: AGLfloatspecifying the minimum level-of-detail value.gl.TEXTURE_WRAP_R: AGLenumspecifying the texture wrapping function for the texture coordinate r.gl.TEXTURE_WRAP_S: AGLenumspecifying the texture wrapping function for the texture coordinate s.gl.TEXTURE_WRAP_T: AGLenumspecifying the texture wrapping function for the texture coordinate t.
param- A
GLint(samplerParameteri) or aGLfloat(samplerParameterf) specifying a value forpname.
Return value
None.
Examples
var sampler = gl.createSampler();
gl.samplerParameteri(sampler, gl.TEXTURE_MAG_FILTER, gl.NEAREST);
