Class GLEnvironment

Namespace: ValveResourceFormat.Renderer
Assembly: Renderer.dll

OpenGL environment initialization and default render state configuration.

public static class GLEnvironment

Inheritance

object ← GLEnvironment

Fields

RequiredVersion

Minimum required OpenGL version.

public static readonly Version RequiredVersion

Field Value

Version

Properties

GpuRendererAndDriver

Gets the GPU renderer name and driver version string.

public static string? GpuRendererAndDriver { get; }

Property Value

string?

IndirectCountSupported

Indicates whether indirect count draw calls are supported by the current driver.

public static bool IndirectCountSupported { get; }

Property Value

bool

SlowMultiDrawIndirect

Indicates whether the driver does not perform efficiently with small sub-draws, making GPU-driven rendering slower than direct draws. Intel drivers also misassign gl_BaseInstance across sub-draws when baseVertex varies within one multidraw.

public static bool SlowMultiDrawIndirect { get; }

Property Value

bool

Methods

EnableParallelShaderCompile()

Allows the driver to compile and link shaders on its own worker threads.

public static void EnableParallelShaderCompile()

Initialize(ILogger)

Initializes the OpenGL environment and queries capabilities.

public static void Initialize(ILogger logger)

Parameters

logger ILogger

Logger for diagnostic output.

Exceptions

NotSupportedException

Thrown if the OpenGL version is too old.

SetDefaultRenderState()

Sets the default OpenGL render state for Source 2 rendering.

public static void SetDefaultRenderState()

To3x4(Matrix4x4)

Converts a to an OpenTK Matrix3x4, transposing the matrix and dropping the last (M14/M24/M34/M44) column.

public static Matrix3x4 To3x4(this Matrix4x4 m)

Parameters

m Matrix4x4

Returns

Matrix3x4

ToOpenTK(Matrix4x4)

Converts a to an OpenTK Matrix4.

public static Matrix4 ToOpenTK(this Matrix4x4 m)

Parameters

m Matrix4x4

Returns

Matrix4
