Detailed Description

[AI] Namespace containing all classes related to the 3D graphics abstraction/rendering engine.

[AI] Used as an abstraction layer over Direct3D (Retained Mode) and device representations in the LEGO Island engine. [AI]

Typedef Documentation

◆ FloatMatrix4

Tgl::FloatMatrix4

[AI] Represents a 4x4 matrix of single-precision floating point values.

[AI] Commonly used for 3D geometric transformations and coordinate operations (such as translation, rotation, or scaling).

Definition at line 53 of file tglvector.h.

Enumeration Type Documentation

◆ ColorModel

enum Tgl::ColorModel

[AI] Represents available color models for rendering.

Not used in the shipped game; exact semantics are inferred. [AI]

[AI] Includes ramp-based or true RGB color models (possibly for palette vs. truecolor rendering). [AI]

Enumerator
Ramp	[AI] Uses a color ramp (palette/indexed color). [AI]
RGB	[AI] Uses direct RGB color values. [AI]

Definition at line 18 of file tgl.h.

◆ LightType

enum Tgl::LightType

[AI] Types of lights supported in the renderer.

[AI]

[AI] Used to define the nature and behavior of a light source—ambient, point, spot, directional, or parallel point. [AI]

Enumerator
Ambient	[AI] Non-directional lighting applied equally everywhere. [AI]
Point	[AI] Light emitted from a point in all directions. [AI]
Spot	[AI] Light that emits a cone-shaped beam from a point. [AI]
Directional	[AI] Parallel light rays, such as sunlight. [AI]
ParallelPoint	[AI] Similar to point, but with parallel rays. [AI]

Definition at line 42 of file tgl.h.

◆ MaterialMode

enum Tgl::MaterialMode

[AI] Determines how material properties are sourced for a group/mesh.

[AI] Specifies if the group's material will be inherited or specified explicitly; inferred from assembly, not present in leaked Tgl code. [AI]

Enumerator
FromParent	[AI] Inherit material from parent. [AI]
FromFrame	[AI] Use material from the current frame. [AI]
FromMesh	[AI] Use material specified at the mesh level. [AI]

Definition at line 75 of file tgl.h.

◆ ProjectionType

enum Tgl::ProjectionType

[AI] Projection modes for camera/view transforms.

[AI]

[AI] Determines whether the scene is rendered with perspective or orthographic projection. [AI]

Enumerator
Perspective	[AI] Distant objects appear smaller. [AI]
Orthographic	[AI] Objects keep constant size regardless of distance. [AI]

Definition at line 55 of file tgl.h.

◆ Result

enum Tgl::Result

[AI] Result type used throughout the Tgl API to report operation success or failure.

[AI]

[AI] Standardizes error handling in the Tgl API. [AI]

Enumerator
Error	[AI] Operation failed. [AI]
Success	[AI] Operation succeeded. [AI]

Definition at line 126 of file tgl.h.

◆ ShadingModel

enum Tgl::ShadingModel

[AI] Represents shading models available for rendering geometry.

[AI]

[AI] Determines the type of lighting and surface shading calculation performed (e.g., wireframe, flat, Gouraud, or Phong shading). [AI]

Enumerator
Wireframe	[AI] No shading; renders only mesh edges. [AI]
UnlitFlat	[AI] Flat shading without lighting calculations. [AI]
Flat	[AI] Flat shaded, possibly single color per polygon with lighting. [AI]
Gouraud	[AI] Gouraud (vertex-interpolated) shading. [AI]
Phong	[AI] Phong (pixel-level) shading, if supported. [AI]

Definition at line 29 of file tgl.h.

◆ TextureMappingMode

enum Tgl::TextureMappingMode

[AI] Methods for mapping textures onto geometry.

[AI]

[AI] Affects perspective correction when rendering textured geometry. [AI]

Enumerator
Linear	[AI] Linear interpolation (faster, less accurate). [AI]
PerspectiveCorrect	[AI] Perspective-correct mapping (higher quality). [AI]

Definition at line 65 of file tgl.h.

Function Documentation

◆ CreateRenderer()

Renderer * Tgl::CreateRenderer ( )

[AI] Instantiates and returns a new Tgl::Renderer implementation.

[AI]

Returns: Renderer* New renderer or nullptr on error. [AI]

Definition at line 8 of file renderer.cpp.

◆ DegreesToRadians()

double Tgl::DegreesToRadians ( double degrees )

inline

[AI] Converts an angle from degrees to radians.

Parameters

degrees Angle in degrees. [AI]

Returns: [AI] Angle converted to radians.

[AI] Uses the mathematical formula: radians = degrees × (π / 180).

Definition at line 32 of file tglvector.h.

◆ RadiansToDegrees()

double Tgl::RadiansToDegrees ( double radians )

inline

[AI] Converts an angle from radians to degrees.

Parameters

radians Angle in radians. [AI]

Returns: [AI] Angle converted to degrees.

[AI] Uses the mathematical formula: degrees = radians × (180 / π).

Definition at line 43 of file tglvector.h.

◆ Succeeded()

int Tgl::Succeeded ( Result result )

inline

[AI] Returns whether a Tgl::Result indicates success.

[AI]

Parameters

result Result to test. [AI]

Returns: int Returns 1 if the result is Tgl::Success, 0 otherwise. [AI]

Definition at line 136 of file tgl.h.
