Problem adding vertex to mesh #60

Closed owenosborn closed 4 years ago

owenosborn commented 4 years ago

When I run the following:

local mesh = of.Mesh()
mesh:setMode(of.PRIMITIVE_POINTS)
local top = glm.vec3(100.0, 50.0, 0.0)
mesh:addVertex(top)

I get this error:

Error in Mesh_addVertex (arg 2), expected 'ofDefaultVertexType *' got 'glm::vec3 *'

Same thing if I use of.Vec3f() for the vertex...Anything to try from lua end? or is this a problem with the bindings?

Hmmm. Strange. It works fine for me on macOS. What versions of OF & ofxLua are you using.

This runs without errors in the luaTests test script:

  local mesh = of.Mesh()
  mesh:addVertex(glm.vec3(1, 2, 3))
  mesh:setMode(of.PRIMITIVE_POINTS)
  local top = glm.vec3(100.0, 50.0, 0.0)
  mesh:addVertex(top)

I'm running linuxarm (Raspberry Pi). OF 0.10.1, ofxLua 1.3.3

Yeah, getting same error out of the test. 

tests.lua:71: Error in Mesh_addVertex (arg 2), expected 'ofDefaultVertexType *' got 'glm::vec3 *'

It a bindings issue were Swig needed to know about the ofDefaultVertexType and is fixed in ofxLua 1.3.6. You can update to 1.3.7 which has bindings for OF 0.10, see the change log.

I can confirm this now works with latest versions of OF and ofxLua. Thanks
