Здесь я зочу добавить золоченые принты на пачке. Для этого понадобится по ходу изменять (подправлять) размеры и позиции проекций.
Новый root01.txt будет такой:

1. Скопируем этот код в Текстовый редактор и сохраним его (overwrite) to/as
C:\CPP\a997modeler\dt\models\misc\marlboro01\root01.txt
Обратите внимание:
- В тагах “a” теперь есть новые параметры/properties: whl (измененный размер) и pxyz (позиция прекции).
- “x” в размерах/координатах означает использовать значение по умолчанию (из виртуальной формы).
- Еще появился новый таг “clone” (последняя строка), который копирует/дублирует последнюю закрытую группу (в этом примере – золоченые принты на лицевой стороне) и размещает ее (копию) на обратной стороне.
В предыдущих примерах мы использовали текстуру gold01.bmp. Но для нашей пачки она слишком желтая. Я добавил еще одну, “римское золото”:
Менее желтую и по-зеленоватее.
2. Сгрузим BMP файл тут
и сохраним его to/as:
C:\CPP\engine\dt\common\img\materials\gold02roman.bmp
Теперь – программная сторона.
Windows
3. Запускаем VS, открываем C:\CPP\a997modeler\p_windows\p_windows.sln.
4. Под modeler добавим новый header file GroupTransform.h
Location: C:\CPP\engine\modeler
Код:
#pragma once
#include "ModelBuilder.h"
class GroupTransform
{
public:
float shift[4] = { 0,0,0,0 };
float spin[3] = { 0,0,0 }; //in degrees
public:
int executeGroupTransform(ModelBuilder* pMB) { return executeGroupTransform(pMB, this); };
static int executeGroupTransform(ModelBuilder* pMB, GroupTransform* pGT);
};
5. Под modeler добавим новый C++ file GroupTransform.cpp
Location: C:\CPP\engine\modeler
Код:
#include "GroupTransform.h"
int GroupTransform::executeGroupTransform(ModelBuilder* pMB, GroupTransform* pGT) {
pMB->moveGroupDg(pMB, pGT->spin[0], pGT->spin[1], pGT->spin[2], pGT->shift[0], pGT->shift[1], pGT->shift[2]);
return 1;
}
В ModelLoader-е – новый функционал:
- fillProps_gt(..) – чтение/заполнение GroupTrandform info.
- processTag_a(..) подправлен для приема под-настроек VirtualShape и обработки GroupTrandform инструкций (которые относятся к исполняемой группе “a”).
- добавлена обработка тага “clone” – processTag_clone(..)
6. Заменим ModelLoader.h код на:
#pragma once
#include "XMLparser.h"
#include "ModelBuilder.h"
#include "GroupTransform.h"
class ModelLoader : public XMLparser
{
public:

if (pMB != NULL) {

}
else {

}
pModelBuilder->useSubjN(subjN);
};
virtual ~ModelLoader() {
if (!ownModelBuilder)
return;
pModelBuilder->buildDrawJobs(*pSubjsVector);
delete pModelBuilder;
};
static int processTag_a(ModelLoader* pML); //apply

static int setTexture(ModelLoader* pML, int* pInt, std::string txName);
