Tri API 3D Sphere problem

I Extracted this code in the forum... but the problem is the texture repeat in each picture...

C++ Source Code:

1	int CSphere :: Draw( float flTime )

3	cl_entity_t *player;

4	vec3_t org;

6	// Load it up with some bogus data

7	player = gEngfuncs.GetLocalPlayer();

8	if ( player )

11	org = player->origin;

13	// org.x += 50;

14	// org.y += 50;

16	if (gHUD.m_hsprCursor == 0)

18	char sz[256];

19	sprintf( sz, "sprites/blastsphere.spr" );

20	gHUD.m_hsprCursor = SPR_Load( sz );

23	gEngfuncs.pTriAPI->SpriteTexture( (struct model_s *)gEngfuncs.GetSpritePointer( gHUD.m_hsprCursor ), 0 );

25	// Create a triangle, sigh

26	gEngfuncs.pTriAPI->RenderMode( kRenderTransAdd );

27	gEngfuncs.pTriAPI->CullFace( TRI_NONE );

28	gEngfuncs.pTriAPI->Brightness( 1 );

29	gEngfuncs.pTriAPI->Color4f( 1.0, 1.0, 1.0, 1.0 );

31	float step = 5;

32	float grad1 = 0;

33	float grad2 = -90;

34	float x, y, z, tmp;

35	float radius = 40;

37	while (grad2 < 90)

40	//gEngfuncs.Con_Printf( "grad2 = %f, z = %f\n", grad2, cos(M_PI * (grad2 / 180)));

42	while (grad1 < 360)

44	gEngfuncs.pTriAPI->Begin( TRI_QUAD_STRIP );

46	z = radius * sin(M_PI * (grad2 / 180));

47	// z = radius;

48	tmp = radius * cos(M_PI * (grad2 / 180));

49	x = cos(M_PI * (grad1 / 180)) * tmp;

50	y = sin(M_PI * (grad1 / 180)) * tmp;

52	// gEngfuncs.Con_Printf( "Rad x1 = %f, y1 = %f, z1 = %f\n", x, y, z);

54	gEngfuncs.pTriAPI->TexCoord2f( 0, 1 );

55	gEngfuncs.pTriAPI->Vertex3f( org.x + x, org.y + y, org.z + z );

57	grad2 += step;

58	z = radius * sin(M_PI * (grad2 / 180));

59	// z = radius;

60	tmp = radius * cos(M_PI * (grad2 / 180));

61	x = cos(M_PI * (grad1 / 180)) * tmp;

62	y = sin(M_PI * (grad1 / 180)) * tmp;

64	// gEngfuncs.Con_Printf( "Rad x2 = %f, y2 = %f, z2 = %f\n", x, y, z);

66	gEngfuncs.pTriAPI->TexCoord2f( 1, 1 );

67	gEngfuncs.pTriAPI->Vertex3f( org.x + x, org.y + y, org.z + z );

69	grad2 -= step;

70	grad1 += step;

71	z = radius * sin(M_PI * (grad2 / 180));

72	// z = radius;

73	tmp = radius * cos(M_PI * (grad2 / 180));

74	x = cos(M_PI * (grad1 / 180)) * tmp;

75	y = sin(M_PI * (grad1 / 180)) * tmp;

77	// gEngfuncs.Con_Printf( "Rad x3 = %f, y3 = %f, z3 = %f\n", x, y, z);

79	gEngfuncs.pTriAPI->TexCoord2f( 0, 0 );

80	gEngfuncs.pTriAPI->Vertex3f( org.x + x, org.y + y, org.z + z );

82	grad2 += step;

83	z = radius * sin(M_PI * (grad2 / 180));

84	// z = radius;

85	tmp = radius * cos(M_PI * (grad2 / 180));

86	x = cos(M_PI * (grad1 / 180)) * tmp;

87	y = sin(M_PI * (grad1 / 180)) * tmp;

89	// gEngfuncs.Con_Printf( "Rad x4 = %f, y4 = %f, z4 = %f\n", x, y, z);

91	gEngfuncs.pTriAPI->TexCoord2f( 1, 0 );

92	gEngfuncs.pTriAPI->Vertex3f( org.x + x, org.y + y, org.z + z );

94	grad2 -= step;

95	gEngfuncs.pTriAPI->End();

98	grad2 += step;

99	grad1 = 0;

  return 1;

Sorry bad english
