VFX Mesh Generator

Useful 3D mesh generator for Visual Effect. It has controllable properties that fits with the usual usecase for making VFX.

✨ Features

• Generate primitive uv mapped 3d mesh with controllable properties
• Edit the mesh dynamically on runtime
• Auto update mesh on editor
• Flip normals
• Save mesh
• Bonus utilites for debugging like debug texture

💻 Generators

• Hollow Circle
• 2 Dimensional Cone
• Half Ring
• Ring
• Free controllable Cone

🔍 API Reference

MeshGenerator

Get the reference by

MeshGenerator generator = GetComponent<MeshGenerator>();

🔗 Syntax

Method	Description
Draw()	Redraw the current mesh to current properties
SaveMesh()	Save the current mesh as file

Properties	Type	Description
FlipNormals	bool	Choose wether to flip the normals or not

📖 Examples

Set the outer radius of the generated 2D Cone to 20 and the angle to 120 degree. Flip the normal. Then redraw the result.

Cone2DMeshGenerator generator = GetComponent<Cone2DMeshGenerator>();
generator.OuterRadius = 20;
generator.Angle = 120;
generator.FlipNormals = true;
generator.Draw();

FreeConeMeshGenerator

Get the reference by

FreeConeMeshGenerator generator = GetComponent<FreeConeMeshGenerator>();

🔗 Syntax

Method	Description
EditVerticesByEquation(float x)	Edit the vertices by math equation with y = f(x). It change the elements of HeightList

Properties	Type	Description
StartHeight	float	The left border of the x of the function
EndHeight	float	The right border of the x of the function
Sides	float	Amount of sides. Also used as resolution of the mesh
Angles	float	Angle of the mesh
HeightList	List<HeightData>	List of height and radius of the vertices. Can be edited manually or edited by EditVerticesByEquation(float x)

📖 Examples

Change the vertices into y = sqrt(x) with x from 0 to 10 which is parabole (inverse of y = x^2).

FreeConeMeshGenerator generator = GetComponent<FreeConeMeshGenerator>();
generator.StartHeight = 0;
generator.StartHeight = 10;
generator.EditVerticesByEquation(x => Mathf.Pow(x, 0.5f));
generator.Draw();
