Mesh

Inherits: Resource < RefCounted < Object

Inherited By: ArrayMesh, ImmediateMesh, PlaceholderMesh, PrimitiveMesh

A Resource that contains vertex array-based geometry.

Description

Mesh is a type of Resource that contains vertex array-based geometry, divided in surfaces. Each surface contains a completely separate array and a material used to draw it. Design wise, a mesh with multiple surfaces is preferred to a single surface, because objects created in 3D editing software commonly contain multiple materials.

Enumerations

enum PrimitiveType:

PrimitiveType PRIMITIVE_POINTS = 0

Render array as points (one vertex equals one point).

PrimitiveType PRIMITIVE_LINES = 1

Render array as lines (every two vertices a line is created).

PrimitiveType PRIMITIVE_LINE_STRIP = 2

Render array as line strip.

PrimitiveType PRIMITIVE_TRIANGLES = 3

Render array as triangles (every three vertices a triangle is created).

PrimitiveType PRIMITIVE_TRIANGLE_STRIP = 4

Render array as triangle strips.

enum ArrayType:

ArrayType ARRAY_VERTEX = 0

PackedVector3Array, PackedVector2Array, or Array of vertex positions.

ArrayType ARRAY_NORMAL = 1

PackedVector3Array of vertex normals.

ArrayType ARRAY_TANGENT = 2

PackedFloat32Array of vertex tangents. Each element in groups of 4 floats, first 3 floats determine the tangent, and the last the binormal direction as -1 or 1.

ArrayType ARRAY_COLOR = 3

PackedColorArray of vertex colors.

ArrayType ARRAY_TEX_UV = 4

PackedVector2Array for UV coordinates.

ArrayType ARRAY_TEX_UV2 = 5

PackedVector2Array for second UV coordinates.

ArrayType ARRAY_CUSTOM0 = 6

Contains custom color channel 0. PackedByteArray if (format >> Mesh.ARRAY_FORMAT_CUSTOM0_SHIFT) & Mesh.ARRAY_FORMAT_CUSTOM_MASK is ARRAY_CUSTOM_RGBA8_UNORM, ARRAY_CUSTOM_RGBA8_UNORM, ARRAY_CUSTOM_RG_HALF or ARRAY_CUSTOM_RGBA_HALF. PackedFloat32Array otherwise.

ArrayType ARRAY_CUSTOM1 = 7

Contains custom color channel 1. PackedByteArray if (format >> Mesh.ARRAY_FORMAT_CUSTOM1_SHIFT) & Mesh.ARRAY_FORMAT_CUSTOM_MASK is ARRAY_CUSTOM_RGBA8_UNORM, ARRAY_CUSTOM_RGBA8_UNORM, ARRAY_CUSTOM_RG_HALF or ARRAY_CUSTOM_RGBA_HALF. PackedFl
