Abstract
An apparatus to display an overlaid image includes an alpha-value-checking unit to check a 3D object having an alpha value among 3D objects of an overlay plane, a blending unit to blend the 3D object and the previously painted overlay plane based on a plurality of blending rules if the 3D object has a predetermined alpha value as a result of the check by the alpha-value-checking unit, and a rendering unit to render the blended 3D object and the previously painted overlay plane.
Claims20
An apparatus to display an overlaid image, the apparatus comprising:
- an alpha-value-checking unit to check a 3D object having an alpha value among 3D objects of a previously painted overlay plane;
- a blending unit to blend the 3D object and the previously painted overlay plane based on a plurality of blending rules, if the 3D object has a predetermined alpha value as a result of the check by the alpha-value-checking unit;
- and
- a rendering unit to render the blended 3D object and the previously painted overlay plane.
A method of displaying an overlaid image, the method comprising:
- checking a 3D object having an alpha value among 3D objects of a previously painted overlay plane;
- blending the 3D object having the alpha value and the previously painted overlay plane based on a plurality of blending rules if the 3D object has a predetermined alpha value as a result of the checking;
- and
- rendering the overlay plane of the 3D object blended through the plurality of blending rules.
A method of displaying an overlaid image, comprising:
- obtaining an alpha value of an object to be blended with an overlay plane;
- a first blending process to blend the object with the overlay plane using a first blending rule and obtaining a first result having a range of alpha values that decreased;
- a second blending process to blend a polygon with the first result using a second blending rule to obtain a second result to increase the range of the alpha values;
- and
- rendering the second result.
An apparatus to display an overlaid image, comprising:
- an alpha-value-checker to obtain an alpha value of an object to be blended with an overlay plane;
- a blender to perform a first blending process to blend the object with the overlay plane using a first blending rule and obtaining a first result having a range of alpha values that decreased, and a second blending process to blend a polygon with the first result using a second blending rule to obtain a second result to increase the range of the alpha values;
- and
- a renderer to rendering the second result.
