Example 1 with ShaderProgramFeature

use of org.terasology.rendering.assets.shader.ShaderProgramFeature in project Terasology by MovingBlocks.

the class GLSLShader method updateAvailableFeatures.

private void updateAvailableFeatures() {
    availableFeatures.clear();
    // Check which features are used in the shaders and update the available features mask accordingly
    for (ShaderProgramFeature feature : ShaderProgramFeature.values()) {
        // TODO: Have our own shader language and parse this stuff out properly
        if (shaderProgramBase.getFragmentProgram().contains(feature.toString())) {
            logger.debug("Fragment shader feature '" + feature.toString() + "' is available...");
            availableFeatures.add(feature);

            logger.debug("Vertex shader feature '" + feature.toString() + "' is available...");
            availableFeatures.add(feature);
        }
    }

Example 3 with ShaderProgramFeature

use of org.terasology.rendering.assets.shader.ShaderProgramFeature in project Terasology by MovingBlocks.

the class GLSLMaterial method recompile.

@Override

        disposalAction.shaderPrograms.put(featureMask, shader.linkShaderProgram(featureMask));
    }
    // resolves #966
    // Some of the uniforms are not updated constantly between frames
    // this function will rebind any uniforms that are not bound
    rebindVariables(materialData);
