RDShaderSPIRV

Inherits: Resource < RefCounted < Object

SPIR-V intermediate representation as part of a RDShaderFile (used by RenderingDevice).

Description

RDShaderSPIRV represents a RDShaderFile‘s SPIR-V code for various shader stages, as well as possible compilation error messages. SPIR-V is a low-level intermediate shader representation. This intermediate representation is not used directly by GPUs for rendering, but it can be compiled into binary shaders that GPUs can understand. Unlike compiled shaders, SPIR-V is portable across GPU models and driver versions.

This object is used by RenderingDevice.

Property Descriptions

PackedByteArray bytecode_compute = PackedByteArray() 🔗

• void set_stage_bytecode(stage: ShaderStage, bytecode: PackedByteArray)

• PackedByteArray get_stage_bytecode(stage: ShaderStage) const

Note: The returned array is copied and any changes to it will not update the original property value. See PackedByteArray for more details.

PackedByteArray bytecode_fragment = PackedByteArray() 🔗

• void set_stage_bytecode(stage: ShaderStage, bytecode: PackedByteArray)

• PackedByteArray get_stage_bytecode(stage: ShaderStage) const

The SPIR-V bytecode for the fragment shader stage.

Note: The returned array is copied and any changes to it will not update the original property value. See PackedByteArray for more details.

PackedByteArray bytecode_tesselation_control = PackedByteArray() 🔗

• void set_stage_bytecode(stage: ShaderStage, bytecode: PackedByteArray)

• PackedByteArray get_stage_bytecode(stage: ShaderStage) const
