zeBlend

Use .new("blend") to create the object. It blends the incoming (source) RGBA values with the RGBA values that are already in the frame buffer (destination). Refer to the OpenGL reference for meanings of parameters. An enabled blending object affects all objects after it in the tree of a scene structure unless the node containing the blending object saves and restores OpenGL attributes of its predecessor.

:set{...}

Sets blending properties with a Lua table. Valid key-value pairs in the Lua table are listed as follows.

Key Value Type Remark
sfactor zero string Sets the source factor as GL_ZERO.
  one string Sets the source factor as GL_ONE.
  one_minus_dst_color string Sets the source factor as GL_ONE_MINUS_DST_COLOR.
  one_minus_dst_alpha string sets the source factor as GL_ONE_MINUS_DST_ALPHA.
  one_minus_src_alpha string sets the source factor as GL_ONE_MINUS_SRC_ALPHA.
  dst_color string sets the source factor as GL_DST_COLOR.
  dst_alpha string sets the source factor as GL_DST_ALPHA.
  src_alpha string sets the source factor as GL_SRC_ALPHA.
  src_alpha_saturate string sets the source factor as GL_SRC_ALPHA_SATURATE.
dfactor zero string Sets the destination factor as GL_ZERO.
  one string Sets the destination factor as GL_ONE.
  one_minus_src_color string Sets the destination factor as GL_ONE_MINUS_SRC_COLOR.
  one_minus_src_alpha string sets the destination factor as GL_ONE_MINUS_SRC_ALPHA.
  one_minus_dst_alpha string sets the destination factor as GL_ONE_MINUS_DST_ALPHA.
  src_color string sest the destination factor as GL_SRC_COLOR.
  src_alpha string sets the destination factor as GL_SRC_ALPHA.
  dst_alpha string sets the destination factor as GL_DST_ALPHA.
zbuffer flag boolean Enables or disables depth buffer test.
enable flag Boolean Enables (default) and disables the object
