int ESUTIL_API esGenCube (  float  scale, GLfloat **  vertices, GLfloat **  normals, GLfloat **  texCoords, GLuint **  indices )

Generates geometry for a cube. Allocates memory for the vertex data and stores the results in the arrays. Generate index list for a TRIANGLES. Parameters: scale  The size of the cube, use 1.0 for a unit cube. vertices  If not NULL, will contain array of float3 positions normals  If not NULL, will contain array of float3 normals texCoords  If not NULL, will contain array of float2 texCoords indices  If not NULL, will contain the array of indices for the triangle strip Returns: The number of indices required for rendering the buffers (the number of indices stored in the indices array if it is not NULL ) as a GL_TRIANGLE_STRIP

int ESUTIL_API esGenSphere (  int  numSlices, float  radius, GLfloat **  vertices, GLfloat **  normals, GLfloat **  texCoords, GLuint **  indices )

Generates geometry for a sphere. Allocates memory for the vertex data and stores the results in the arrays. Generate index list for a TRIANGLE_STRIP. Parameters: numSlices  The number of slices in the sphere vertices  If not NULL, will contain array of float3 positions normals  If not NULL, will contain array of float3 normals texCoords  If not NULL, will contain array of float2 texCoords indices  If not NULL, will contain the array of indices for the triangle strip Returns: The number of indices required for rendering the buffers (the number of indices stored in the indices array if it is not NULL ) as a GL_TRIANGLE_STRIP
