Interface IntVertexData

All Superinterfaces:
com.badlogic.gdx.utils.Disposable
All Known Implementing Classes:
VertexArray, VertexBufferObject, VertexBufferObjectInstanced, VertexBufferObjectSubData, VertexBufferObjectWithVAO
public interface IntVertexData extends com.badlogic.gdx.utils.Disposable
A VertexData instance holds vertices for rendering with OpenGL. It is implemented as either a VertexArray or a VertexBufferObject. Only the later supports OpenGL ES 2.0.

  • Method Details

    • getNumVertices

      int getNumVertices()
      Returns:
      the number of vertices this VertexData stores

    • getNumMaxVertices

      int getNumMaxVertices()
      Returns:
      the number of vertices this VertedData can store

    • getAttributes

      com.badlogic.gdx.graphics.VertexAttributes getAttributes()
      Returns:
      the VertexAttributes as specified during construction.

    • setVertices

      void setVertices(float[] vertices, int offset, int count)
      Sets the vertices of this VertexData, discarding the old vertex data. The count must equal the number of floats per vertex times the number of vertices to be copied to this VertexData. The order of the vertex attributes must be the same as specified at construction time via VertexAttributes.

      This can be called in between calls to bind and unbind. The vertex data will be updated instantly.

      Parameters:
      vertices - the vertex data
      offset - the offset to start copying the data from
      count - the number of floats to copy

    • updateVertices

      void updateVertices(int targetOffset, float[] vertices, int sourceOffset, int count)
      Update (a portion of) the vertices. Does not resize the backing buffer.
      Parameters:
      vertices - the vertex data
      sourceOffset - the offset to start copying the data from
      count - the number of floats to copy

    • getBuffer

      FloatBuffer getBuffer()
      Returns the underlying FloatBuffer and marks it as dirty, causing the buffer contents to be uploaded on the next call to bind. If you need immediate uploading use setVertices(float[], int, int); Any modifications made to the Buffer *after* the call to bind will not automatically be uploaded.
      Returns:
      the underlying FloatBuffer holding the vertex data.

    • bind

      void bind(ExtShaderProgram shader)
      Binds this VertexData for rendering via glDrawArrays or glDrawElements.

    • bind

      void bind(ExtShaderProgram shader, int[] locations)
      Binds this VertexData for rendering via glDrawArrays or glDrawElements.
      Parameters:
      locations - array containing the attribute locations.

    • unbind

      void unbind(ExtShaderProgram shader)
      Unbinds this VertexData.

    • unbind

      void unbind(ExtShaderProgram shader, int[] locations)
      Unbinds this VertexData.
      Parameters:
      locations - array containing the attribute locations.

    • invalidate

      void invalidate()
      Invalidates the VertexData if applicable. Use this in case of a context loss.

    • dispose

      void dispose()
      Disposes this VertexData and all its associated OpenGL resources.
      Specified by:
      dispose in interface com.badlogic.gdx.utils.Disposable
