Usage Patterns

Section titled “Usage Patterns”

Basic Rendering

Section titled “Basic Rendering”
// Example: Basic rendering setup
RenderSystem.assertOnRenderThread();
RenderSystem.setShaderTexture(0, texture);
RenderSystem.setShaderColor(1.0f, 1.0f, 1.0f, 1.0f);


// Render geometry
VertexConsumer consumer = bufferSource.getBuffer(renderType);
// ... vertex submission

Custom Render Types

Section titled “Custom Render Types”
// Example: Creating custom render type
RenderType customType = RenderType.builder()
    .setTransparencyState(TransparencyState.TRANSLUCENT)
    .setTextureState(new TextureState(textureLocation, false, false))
    .setCullState(CullState.NO_CULL)
    .setShaderState(RENDERTYPE_ENTITY_TRANSLUCENT_SHADER)
    .build("custom_type");

Shader Integration

Section titled “Shader Integration”
// Example: Custom shader setup
ShaderInstance shader = new ShaderInstance(resourceProvider, "custom_shader", format);
shader.safeGetUniform("uniformName").set(value);
RenderSystem.setShader(() -> shader);

Migration Notes

Section titled “Migration Notes”

This documentation covers Minecraft 26.1 specifically. Key changes from previous versions:

  • Enhanced Blaze3D integration with improved abstractions
  • Thread safety enforcement for all rendering operations
  • Improved shader pipeline with better debugging support
  • Performance optimizations throughout the rendering system
