Class MaterialCompiler

java.lang.Object

dev.engine.graphics.common.material.MaterialCompiler

public final class MaterialCompiler
extends Object

Compiles material properties into shader code and GPU-uploadable data.

This bridges the gap between the user's property bag (MaterialData) and the GPU's typed buffers + shader structs. The user never writes shader code for standard materials — this generates everything automatically.

Method Summary

Modifier and Type	Method	Description
static String	generateMaterialCbuffer(MaterialData mat, int binding)	Generates a Slang cbuffer with the material's properties inlined.
static String	generateMaterialStruct(MaterialData mat)	Generates a Slang struct definition from the material's actual properties.
static String	injectMaterialData(String source, MaterialData mat, int binding)	Injects material struct/cbuffer into shader source, replacing the // __MATERIAL_DATA__ placeholder.
static void	registerType(Class<?> javaType, String slangType, int sizeInBytes)	Registers a custom type for material → Slang mapping.
static ByteBuffer	serializeMaterialData(MaterialData mat)	Serializes the material's property values into a ByteBuffer for GPU upload.
static String	shaderKey(MaterialData mat)	Derives a shader key from a material's shaderHint + property set.

Method Details

shaderKey

public static String shaderKey(MaterialData mat)

Derives a shader key from a material's shaderHint + property set. Same key = same shader variant. Different properties = different key.

generateMaterialStruct

public static String generateMaterialStruct(MaterialData mat)

Generates a Slang struct definition from the material's actual properties.

generateMaterialCbuffer

public static String generateMaterialCbuffer(MaterialData mat,
 int binding)

Generates a Slang cbuffer with the material's properties inlined.

serializeMaterialData

public static ByteBuffer serializeMaterialData(MaterialData mat)

Serializes the material's property values into a ByteBuffer for GPU upload. Properties are laid out in the same order as the generated struct.

injectMaterialData

public static String injectMaterialData(String source,
 MaterialData mat,
 int binding)

Injects material struct/cbuffer into shader source, replacing the // __MATERIAL_DATA__ placeholder.

registerType

public static void registerType(Class<?> javaType,
 String slangType,
 int sizeInBytes)

Registers a custom type for material → Slang mapping.
