Examples with RenderTarget com.mojang.blaze3d.pipeline.RenderTarget used on opensource projects

Example 1 with RenderTarget

use of com.mojang.blaze3d.pipeline.RenderTarget in project Iris by IrisShaders.

the class DeferredWorldRenderingPipeline method prepareRenderTargets.

private void prepareRenderTargets() {
    // Make sure we're using texture unit 0 for this.
    RenderSystem.activeTexture(GL15C.GL_TEXTURE0);
    RenderTarget main = Minecraft.getInstance().getMainRenderTarget();
    renderTargets.resizeIfNeeded(main.width, main.height);
    final ImmutableList<ClearPass> passes;
    if (renderTargets.isFullClearRequired()) {
        renderTargets.onFullClear();
        passes = clearPassesFull;
    } else {
        passes = clearPasses;
    }
    Vector3d fogColor3 = CapturedRenderingState.INSTANCE.getFogColor();
    // NB: The alpha value must be 1.0 here, or else you will get a bunch of bugs. Sildur's Vibrant Shaders
    // will give you pink reflections and other weirdness if this is zero.
    Vector4f fogColor = new Vector4f((float) fogColor3.x, (float) fogColor3.y, (float) fogColor3.z, 1.0F);
    for (ClearPass clearPass : passes) {
        clearPass.execute(fogColor);
    }
}

Example 2 with RenderTarget

use of com.mojang.blaze3d.pipeline.RenderTarget in project Iris by IrisShaders.

the class CompositeRenderer method renderAll.

public void renderAll() {
    RenderSystem.disableBlend();
    RenderSystem.disableAlphaTest();
    final RenderTarget main = Minecraft.getInstance().getMainRenderTarget();
    final int baseWidth = main.width;
    final int baseHeight = main.height;
    FullScreenQuadRenderer.INSTANCE.begin();
    for (Pass renderPass : passes) {
        if (!renderPass.mipmappedBuffers.isEmpty()) {
            RenderSystem.activeTexture(GL15C.GL_TEXTURE0);
            for (int index : renderPass.mipmappedBuffers) {
                setupMipmapping(renderTargets.get(index), renderPass.stageReadsFromAlt.contains(index));
            }
        }
        float scaledWidth = baseWidth * renderPass.viewportScale;
        float scaledHeight = baseHeight * renderPass.viewportScale;
        RenderSystem.viewport(0, 0, (int) scaledWidth, (int) scaledHeight);
        renderPass.framebuffer.bind();
        renderPass.program.use();
        FullScreenQuadRenderer.INSTANCE.renderQuad();
    }
    FullScreenQuadRenderer.end();
    // Make sure to reset the viewport to how it was before... Otherwise weird issues could occur.
    // Also bind the "main" framebuffer if it isn't already bound.
    main.bindWrite(true);
    GlStateManager._glUseProgram(0);
    // NB: Unbinding all of these textures is necessary for proper shaderpack reloading.
    for (int i = 0; i < SamplerLimits.get().getMaxTextureUnits(); i++) {
        // Unbind all textures that we may have used.
        // NB: This is necessary for shader pack reloading to work propely
        RenderSystem.activeTexture(GL15C.GL_TEXTURE0 + i);
        RenderSystem.bindTexture(0);
    }
    RenderSystem.activeTexture(GL15C.GL_TEXTURE0);
