Examples with FBO org.terasology.engine.rendering.opengl.FBO used on opensource projects

Example 1 with FBO

use of org.terasology.engine.rendering.opengl.FBO in project Terasology by MovingBlocks.

the class ModuleRendering method generateWithDimensions.

/**
 *TODO UPDATE the javadoc, this method has been taken from abstractfbomanager during DAG Enhancement project
 * Generates and returns an FBO as characterized by the FboConfig and the dimensions arguments.
 *
 * Notice that if the name of the FBO being generated matches the name of an FBO already stored
 * by the manager, the latter will be overwritten. However, the GPU-side Frame Buffer associated
 * with the overwritten FBO is not disposed by this method.
 *
 * As such, this method should be used only after the relevant checks are made and any
 * pre-existing FBO with the same name as the new one is appropriately disposed.
 *
 * This method produces errors in the log in case the FBO generation process results in
 * FBO.Status.INCOMPLETE or FBO.Status.UNEXPECTED.
 *
 * @param fboConfig an FboConfig object providing FBO configuration details.
 * @param dimensions an FBO.Dimensions instance providing the dimensions of the FBO.
 * @return an FBO instance
 */

Example 2 with FBO

use of org.terasology.engine.rendering.opengl.FBO in project Terasology by MovingBlocks.

the class ShadowMapResolutionDependentFbo method propertyChange.

/**
 * Triggers the regeneration of the shadow map FBOs, if necessary.
 *
 * Once triggered this method checks if "dynamic shadows" are enabled.
 * If dynamics shadows are enabled it obtains the new Shadow Map resolution from the event
 * passed to the method and regenerates the shadow map FBOs.

Example 3 with FBO

use of org.terasology.engine.rendering.opengl.FBO in project Terasology by MovingBlocks.

the class AbstractNode method requiresFbo.

/**

 * The characteristics of the required FBO are described in the fboConfig provided in input.
 * Within the context of the given fboManager an fboConfig uniquely identifies the FBO:
 * if the FBO exists already it is returned, if it doesn't, the FBO is first created and then returned.
 *
 * If the fboManager already contains an FBO with the same fboUri but different characteristics from
 * those described in the fboConfig object, an IllegalArgumentException is thrown.
 *
 * @param fboConfig an FboConfig object describing the required FBO.
 * @param fboManager a BaseFboManager object from which to obtain the FBO.
 * @return the requested FBO object, either newly created or a pre-existing one.
 * @throws IllegalArgumentException if the fboUri in fboConfig already in use by FBO with different characteristics.

Example 5 with FBO

 * or twice, each time with a different rendering stage, when rendering to the head mounted display.
 * <p>

 * provide statistics regarding the ongoing rendering and its individual steps (i.e. rendering shadows, reflections,
 * 2D filters...).
