Interface VanillaInstancedMeshRenderer

All Known Implementing Classes:

InstancedStaticPartRenderer

public interface VanillaInstancedMeshRenderer

Contract for the vanilla VBO instanced renderer — the code path active when no external shader pack (Iris/Oculus) is loaded.

Implemented by InstancedStaticPartRenderer; logic may later move into a dedicated class without changing this API surface.

Method Summary

Modifier and Type	Method	Description
void	addInstance(com.mojang.blaze3d.vertex.PoseStack poseStack, int packedLight, net.minecraft.core.BlockPos blockPos, net.minecraft.world.level.block.entity.BlockEntity blockEntity, net.minecraft.client.renderer.MultiBufferSource bufferSource)	Enqueue one instance into the per-frame batch buffer for the next flush(Matrix4f).
void	cleanup()	GL resource teardown (instance VBO, instance FloatBuffer, companion mesh).
void	flush()	Convenience entry that pulls the projection from RenderSystem.
void	flush(org.joml.Matrix4f projectionMatrix)	Emit a single glDrawElementsInstanced for the accumulated batch using the projection matrix from the current render stage.
int	getInstanceCount()
boolean	isInitialized()
void	renderSingle(com.mojang.blaze3d.vertex.PoseStack poseStack, int packedLight, net.minecraft.core.BlockPos blockPos, net.minecraft.world.level.block.entity.BlockEntity blockEntity, net.minecraft.client.renderer.MultiBufferSource bufferSource)	Single-machine immediate draw on the vanilla instanced shader path.

Method Details

renderSingle

void renderSingle(com.mojang.blaze3d.vertex.PoseStack poseStack,
 int packedLight,
 net.minecraft.core.BlockPos blockPos,
 @Nullable
 net.minecraft.world.level.block.entity.BlockEntity blockEntity,
 @Nullable
 net.minecraft.client.renderer.MultiBufferSource bufferSource)

Single-machine immediate draw on the vanilla instanced shader path.

Source: InstancedStaticPartRenderer#renderSingle(PoseStack, int, BlockPos, BlockEntity, MultiBufferSource) — specifically the --- VANILLA VBO PATH --- branch after the isExternalShaderActive() early-out.

addInstance

void addInstance(com.mojang.blaze3d.vertex.PoseStack poseStack,
 int packedLight,
 net.minecraft.core.BlockPos blockPos,
 @Nullable
 net.minecraft.world.level.block.entity.BlockEntity blockEntity,
 @Nullable
 net.minecraft.client.renderer.MultiBufferSource bufferSource)

Enqueue one instance into the per-frame batch buffer for the next flush(Matrix4f).

Source: InstancedStaticPartRenderer#addInstance(PoseStack, int, BlockPos, BlockEntity, MultiBufferSource) — the vanilla accumulation portion (everything below the Iris/shadow-pass early-outs, including the LightSampleCache 8/16-corner sampling and the float-buffer record write at the bottom).

flush

void flush(org.joml.Matrix4f projectionMatrix)

Emit a single glDrawElementsInstanced for the accumulated batch using the projection matrix from the current render stage.

Source: InstancedStaticPartRenderer#flush() and InstancedStaticPartRenderer#flush(Matrix4f) (the dispatch entry-point), backed by InstancedStaticPartRenderer#flushBatchVanilla(Matrix4f) for the actual draw.

flush

void flush()

Convenience entry that pulls the projection from RenderSystem. Source: InstancedStaticPartRenderer#flush().

getInstanceCount

int getInstanceCount()

Returns:

number of instances currently accumulated in the batch buffer. Source: InstancedStaticPartRenderer#getInstanceCount().

isInitialized

boolean isInitialized()

Returns:

whether the underlying VAO/VBO/EBO triple was successfully created and the renderer is ready to draw. Source: InstancedStaticPartRenderer#isInitialized().

cleanup

void cleanup()

GL resource teardown (instance VBO, instance FloatBuffer, companion mesh). Source: InstancedStaticPartRenderer#cleanup().
