Convert any text to a 3d mesh using any font style

Font23D

Font23D is a C++ library for creating a 3d mesh of any Text in the given True type font.

Demo: Font23D running on browser using webassembly

Compile the code

Install the dependancies

sudo apt install libfreetype6-dev

Now just run the bash script to get the OBJ file output.

sh compile.sh

Sample Outputs

Below outputs are generated using different fonts

Unicode Support

Instruction to use:

• The Library uses FreeType Library to decode the fonts and converts the Text into Vector.
• Then the vector data is converted into triangles using Ploy2Tri library.
• This gives us the triangles of the complete text in a plane.
• The plane is then extruded into 3d object and then creates a closed mesh.
• The Mesh is then saved as OBJ file.

Plans for Future:

• Support WebAssembly and create sample web page to convert input text using uploaded font to 3D mesh.

Contributions:

• Thanks to J.Scheurich from White Dune Project for suggesting fixes for Face culling.
• Thanks to DaegyuMin for fixing a bug in missing triangle.

Generated Mesh has missing face.

Describe the bug

at 2021-02-06, in master branch

below Font2OBJ.cpp file has a bug that generated mesh has missing face.

for(size_t p = 0; p < contour->PointCount() - 1; ++p) {
const double* d1 = contour->GetPoint(p);
const double* d2 = contour->GetPoint(p + 1);

this code can be changed to fix bug.

for(size_t p = 0; p < contour->PointCount(); ++p) {
const double* d1 = contour->GetPoint(p);
const double* d2 = contour->GetPoint(
(p == contour->PointCount() - 1)?(0):(p + 1)
);

Way to have only front face of text

The only way to get something similar to this is to set extrude, bevelRadius, and bevelSteps to zero but there are still the side faces and back face.

I think that a good way to implement this would be to add a new function that would do this.

Also, you should put how to use the functions provided in the respiratory in the readme.

Cannot get the code to compile - compiler error on ubuntu gcc

Describe the bug
Cannot compile the code using sh compile.sh

To Reproduce

1. I'm using gcc version 9.3.0 (Ubuntu 9.3.0-10ubuntu2)
2. I've installed libfreetype6-dev
3. error showing on compiling - mesh.h: In member function ‘int Mesh::addVertex(Vertex)’:
   mesh.h:41:90: error: no matching function for call to ‘find(std::vector::iterator, std::vector::iterator, Vertex&)’
   41 | std::vector::iterator itr = std::find(vertices.begin(), vertices.end(), v);
   | ^

Desktop (please complete the following information):

• OS: Windows 10 / running ubuntu as WSL

The speed is too slow.

hash table can be used in Mesh.addVertex to improve

can i use this as c++ or c# on windows . can you help upload also visualstudio file please

can you upload sample to work on windows , i try to include the code in gui on c++ i coudnt can you help please
