  • Method Details

    • getName

      String getName()
      Returns the name of this vertex attribute.
      Returns:
      the name of this vertex attribute

    • getSemantics

      ILspVertexAttribute.AttributeSemantics getSemantics()
      Returns the semantics of this vertex attribute.
      Returns:
      the semantics of this vertex attribute

    • getType

      ILspVertexAttribute.AttributeType getType()
      Returns the primitive type of this vertex attribute.
      Returns:
      the primitive type of this vertex attribute

    • getComponentCount

      int getComponentCount()
      Returns the number of components used by this vertex attribute. For instance, normal vectors typically have 3 components (X, Y and Z).
      Returns:
      the number of components used by this vertex attribute

    • getStride

      int getStride()
      Returns the distance (in bytes) between two consecutive elements of this vertex attribute in memory.
      Returns:
      the distance (in bytes) between two consecutive elements of this vertex attribute in memory

    • getOffset

      int getOffset()
      Returns the offset (in bytes) from the start of the vertex array data buffer to the first occurrence of this vertex attribute.
      Returns:
      the offset (in bytes) from the start of the vertex array data buffer to the first occurrence of this vertex attribute

    • isInterleaved

      boolean isInterleaved()
      Returns true if the data of this attribute is interleaved with that of other attributes. Otherwise, the data for each vertex attribute is stored as a continuous block.
      Returns:
      true if the data for this vertex attribute is stored in an interleaved fashion

    • isNormalized

      boolean isNormalized()
      For non-floating point attributes, indicates whether the attribute's values should be normalized or not. For a byte attribute, for example, setting this property to true would result in values in [0, 1] going to the vertex shader, whereas setting the property to false would pass on the unmodified values in the [0, 255] range.
      Returns:
      whether this attribute should be normalized
