Pass:drawPart

Edit

Draws a single mesh or part of a mesh in a Model.

Meshes in models can be split into multiple "parts", where each part has its own draw mode and material. This function can draw a single one of these parts, or all of the parts in a single mesh.

Drawing individual meshes or parts is useful because it allows for materials, graphics states, and shader uniforms to be changed in between each draw.

Pass:drawPart(model, mesh, x, y, z, scale, angle, ax, ay, az, instances)
Pass:drawPart(model, mesh, position, scale3, orientation, instances)
Pass:drawPart(model, mesh, transform, instances)
Pass:drawPart(model, mesh, part, x, y, z, scale, angle, ax, ay, az, instances)
Pass:drawPart(model, mesh, part, position, scale3, orientation, instances)
Pass:drawPart(model, mesh, part, transform, instances)

Example

function lovr.draw(pass)
  for node, mesh in model:meshes() do
    local x, y, z, scale, _, _, angle, ax, ay, az = model:getNodeTransform(node)

    for part = 1, model:getMeshPartCount(mesh) do
      pass:drawPart(model, mesh, part, x, y, z, scale, angle, ax, ay, az)
    end
  end
end
