Texture Filter Manager

Name: tessl/npm-gl
Author: tessl

A utility for managing texture sampling configurations in WebGL 2, allowing dynamic switching between different filtering modes without modifying texture parameters.

Capabilities

Sampler Creation

Creates a sampler object and configures it with NEAREST filtering for both minification and magnification @test
Creates a sampler object with LINEAR filtering and CLAMP_TO_EDGE wrapping @test

Sampler Binding

Binds a sampler to texture unit 0 and verifies it affects texture sampling @test
Binds different samplers to multiple texture units simultaneously @test

Sampler Parameter Management

Sets sampler minification filter to NEAREST and magnification filter to LINEAR @test
Configures sampler wrap modes for S and T coordinates independently @test

Implementation

@generates

API

/**
 * Creates and configures a sampler object with specified filtering parameters.
 *
 * @param {WebGL2RenderingContext} gl - The WebGL 2 rendering context.
 * @param {Object} options - Configuration options for the sampler.
 * @param {number} options.minFilter - Minification filter (e.g., gl.NEAREST, gl.LINEAR).
 * @param {number} options.magFilter - Magnification filter (e.g., gl.NEAREST, gl.LINEAR).
 * @param {number} [options.wrapS] - S-coordinate wrapping mode (default: gl.CLAMP_TO_EDGE).
 * @param {number} [options.wrapT] - T-coordinate wrapping mode (default: gl.CLAMP_TO_EDGE).
 * @returns {WebGLSampler} The created sampler object.

 * Binds a sampler object to a specified texture unit.
