Importing your model to a cart

Loading a model into the editor

In order to convert an .obj file to a format which this editor supports, you can use this Python script.

Importing a painted model into the Gryphon 3D Engine library

function read_colored_face()
	f={}
	--verts 1 to 3 + 2 color values
	for i=1,5 do
		text=sub(cur_string,cur_string_index,cur_string_index+2)
		value=read_byte(text)
		f[i]=value
		cur_string_index+=2
	end
	return f
end	

function read_colored_face_string(string)
	face_list={}
	load_string(string)
	while(cur_string_index<#string)do
		face=read_colored_face()
		add(face_list,face)
	end
		return face_list
end

function load_model_scene()
	c_mode = k_preset_color -- to show colors of faces
	model_v = read_vector_string(model_v_string)
	model_f = read_colored_face_string(model_f_string)
	model = load_object(model_v, model_f, 0, 0, 0, 0, 0, 0, false, c_mode, 4)
end

scene_index=1
scene_list=
{
{load_model_scene, update_model_scene, draw_background}
}

Example models you can import (copy to clipboard and then press scissor icon)
